  3. Ethical dilemmas in today's nuclear medicine and radiology practice.

    PubMed

    Barron, Bruce J; Kim, E Edmund

    2003-11-01

    Throughout history, societies have developed their own codes of ethics, including those pertaining to the practice of medicine. In the United States, physicians have adopted a set of ethics based on religious values and historical teachings. We, as physicians, have been presented several codes of ethics, including the American Medical Association Code of Ethics and the American College of Radiology Code of Ethics. Over time, we have learned to appropriately apply these codes to our daily practice. With the advent of new technologies in imaging, we may lose sight as to the transfer of these principles to reflect current conditions. Recent history has shown a trend of new technology leading to potential misuse of this technology and further leading to stricter governmental regulations. It is the purpose of this review to give guidelines for dealing with new technologies, such as PET imaging, and we describe a radiologist's ethical responsibility in a doctor-patient relationship. A historical review of medical ethics will lead to discussions about various issues affecting radiologists and nuclear physicians. To be sure, not all ethical situations are black and white, and therefore there are many gray areas. The opinions expressed in this article are those of the authors and are based on extension of already established rules of ethical conduct. PMID:14602866

  13. Radiology. Diagnosis/imaging/intervention. 5 volumes. Annual revision service

    SciTech Connect

    Taveras, J.M.; Ferrucci, J.T.

    1986-01-01

    This five-volume loose leaf work of approximately 4,500 pages is designed to be used as a clinical reference in modern radiologic practice. It covers all aspects of diagnostic imaging, starting with the physical foundation of each imaging modality. The material is organized according to organ systems and not along technical considerations. Thus, when discussing a disease process in any organ, all imaging modalities that can be brought to bear on the diagnosis of an entity are discussed. The volumes are lavishly illustrated, containing about 7,000 black-and-white illustrations and about 50 tables. The five volumes contain nine sections. The discussions of the organ systems are illustrated using examples from plain film, nuclear medicine, computerized tomography, magnetic resonance, position emission tomography and ultrasound. Wherever possible, each chapter begins with a discussion of anatomy, physiology, and general examination technique, and then proceeds to a discussion of disease categories. The loose leaf approach allows for updating of the contents each year through the annual revision service.

  13. Radiological status report for the EBWR containment building. Volume 1: Summary and analysis

    SciTech Connect

    Murdoch, B.T.

    1996-02-01

    At the conclusion of the EBWR D and D process, ANL Health Physics conducted a release survey to determine the radiological status of the facility. The primary goal of the survey was to verify that residual activities on building surfaces met DOE and ANL guidelines for downposting of a Radiologically Contaminated Area to a Radiologically Controlled Area. The resultant area was to bear no contamination designation, with no requirements for radiological personnel monitoring or protective clothing. ANL Health Physics designed a survey procedure, using a graded approach considering the building history, the D and D process, and the intended future use. The survey followed the general guidance of NRC NUREG/CR-5849, but simplified and reduced in scope to match the release goal. The building interior surfaces were divided into 15 principal survey units and one special survey unit. Each of the principal survey units had to meet the controlled release guidelines. The procedure consisted of dual full floor scans for beta/gamma activity, sampling measurements of total and removable alpha and beta/gamma activities, and background gamma exposure surveys. In the 15 principal survey units, surface activities were measured at a total of 444 locations. With the exception of certain excluded contaminated areas and mechanical equipment, the building interior meets the limited release guidelines.

  16. Contraception today.

    PubMed

    Benagiano, Giuseppe; Bastianelli, Carlo; Farris, Manuela

    2006-12-01

    Modern contraceptive methods represent more than a technical advance: they are the instrument of a true social revolution-the "first reproductive revolution" in the history of humanity, an achievement of the second part of the 20th century, when modern, effective methods became available. Today a great diversity of techniques have been made available and-thanks to them, fertility rates have decreased from 5.1 in 1950 to 3.7 in 1990. As a consequence, the growth of human population that had more than tripled, from 1.8 to more than 6 billion in just one century, is today being brought under control. At the turn of the millennium, all over the world, more than 600 million married women are using contraception, with nearly 500 million in developing countries. Among married women, contraceptive use rose in all but two developing countries surveyed more than once since 1990. Among unmarried, sexually active women, it grew in 21 of 25 countries recently surveyed. Hormonal contraception, the best known method, first made available as a daily pill, can today be administered through seven different routes: intramuscularly, intranasally, intrauterus, intravaginally, orally, subcutaneously, and transdermally. In the field of oral contraception, new strategies include further dose reduction, the synthesis of new active molecules, and new administration schedules. A new minipill (progestin-only preparation) containing desogestrel has been recently marketed in a number of countries and is capable of consistently inhibiting ovulation in most women. New contraceptive rings to be inserted in the vagina offer a novel approach by providing a sustained release of steroids and low failure rates. The transdermal route for delivering contraceptive steroids is now established via a contraceptive patch, a spray, or a gel. The intramuscular route has also seen new products with the marketing of improved monthly injectable preparations containing an estrogen and a progestin. After the first

    1997-07-01

    Building 2 on the US Department of Energy (DOE) Grand Junction Office (GJO) site is part of the GJO Remedial Action Program (GJORAP). During evaluation of Building 2 for determination of radiological release disposition, some inaccessible surface contamination measurements were detected to be greater than the generic surface contamination guidelines of DOE Order 5400.5 (which are functionally equivalent to US Nuclear Regulatory Commission [NRC] Regulatory Guide 1.86). Although the building is nominal in size, it houses the site telecommunications system, that is critical to continued GJO operations, and demolition is estimated at $1.9 million. Because unrestricted release under generic surface contamination guidelines is cost-prohibitive, supplemental standards consistent with DOE Order 5400.5 are being pursued. This report describes measurements and dose analysis modeling efforts to evaluate the radiation dose to members of the public who might occupy or demolish Building 2, a 2,480 square-foot (ft) building constructed in 1944. The north portion of the building was used as a shower facility for Manhattan Project uranium-processing mill workers and the south portion was a warehouse. Many originally exposed surfaces are no longer accessible for contamination surveys because expensive telecommunications equipment have been installed on the floors and mounted on panels covering the walls. These inaccessible surfaces are contaminated above generic contamination limits.

    2015-01-01

    Background Current measurement of the single longest dimension of a polyp is subjective and has variations among radiologists. Our purpose was to develop a computerized measurement of polyp volume in computed tomography colonography (CTC). Methods We developed a 3D automated scheme for measuring polyp volume at CTC. Our scheme consisted of segmentation of colon wall to confine polyp segmentation to the colon wall, extraction of a highly polyp-like seed region based on the Hessian matrix, a 3D volume growing technique under the minimum surface expansion criterion for segmentation of polyps, and sub-voxel refinement and surface smoothing for obtaining a smooth polyp surface. Our database consisted of 30 polyp views (15 polyps) in CTC scans from 13 patients. Each patient was scanned in the supine and prone positions. Polyp sizes measured in optical colonoscopy (OC) ranged from 6-18 mm with a mean of 10 mm. A radiologist outlined polyps in each slice and calculated volumes by summation of volumes in each slice. The measurement study was repeated 3 times at least 1 week apart for minimizing a memory effect bias. We used the mean volume of the three studies as “gold standard”. Results Our measurement scheme yielded a mean polyp volume of 0.38 cc (range, 0.15-1.24 cc), whereas a mean “gold standard” manual volume was 0.40 cc (range, 0.15-1.08 cc). The “gold-standard” manual and computer volumetric reached excellent agreement (intra-class correlation coefficient =0.80), with no statistically significant difference [P (F≤f) =0.42]. Conclusions We developed an automated scheme for measuring polyp volume at CTC based on Hessian matrix-based shape extraction and volume growing. Polyp volumes obtained by our automated scheme agreed excellently with “gold standard” manual volumes. Our fully automated scheme can efficiently provide accurate polyp volumes for radiologists; thus, it would help radiologists improve the accuracy and efficiency of polyp volume

  7. Force protection: today's reality.

    PubMed

    2004-11-11

    Most US infrastructure and major chemical manufacturing facilities as well as their supporting utility systems are inherently vulnerable to a terrorist attack. Force protection is a military and civilian term used to protect personnel and critical facilities and assets against would-be aggressors or terrorists. The war on terrorism is a 200-300-year war. Terrorist attacks on US soil could become as common-place as in the State of Israel. It is very easy to penetrate infrastructure or plants as evidenced by vulnerability assessments performed for states, cities, plants, and military facilities by Versar and others around the country. Chemical, biological, radiological, nuclear, and explosive weapons can be readily used to attack facilities in the US. This paper will explain some of those vulnerabilities, outline the current DoD standard as it relates to vulnerability assessments, and explain how this may be used in commercial applications to deter potential aggressors.

    A hundred years after its birth, general relativity has become a highly successful theory in the sese that it has passed many experimental and observational tests and finds widespread application to diverse set of cosmic phenomena. It remains an accurate research field as more tests are deployed, epitomized by the exciting prospect of detecting gravitational radiation directly. General realtivity is the essential foundation of modern cosmology and underlies our detailed description of the black holes and neutron stars that are ultimately responsible for the most powerful and dramatic cosmic sources. The interface with physics on both the largest and the smallest scales continues to be very fertile. In this talk I will attempt to highlight some key steps along the way to general relativity today.

  11. Radiology's value chain.

    PubMed

    Enzmann, Dieter R

    2012-04-01

    A diagnostic radiology value chain is constructed to define its main components, all of which are vulnerable to change, because digitization has caused disaggregation of the chain. Some components afford opportunities to improve productivity, some add value, while some face outsourcing to lower labor cost and to information technology substitutes, raising commoditization risks. Digital image information, because it can be competitive at smaller economies of scale, allows faster, differential rates of technological innovation of components, initiating a centralization-to-decentralization technology trend. Digitization, having triggered disaggregation of radiology's professional service model, may soon usher in an information business model. This means moving from a mind-set of "reading images" to an orientation of creating and organizing information for greater accuracy, faster speed, and lower cost in medical decision making. Information businesses view value chain investments differently than do small professional services. In the former model, producing a better business product will extend image interpretation beyond a radiologist's personal fund of knowledge to encompass expanding external imaging databases. A follow-on expansion with integration of image and molecular information into a report will offer new value in medical decision making. Improved interpretation plus new integration will enrich and diversify radiology's key service products, the report and consultation. A more robust, information-rich report derived from a "systems" and "computational" radiology approach will be facilitated by a transition from a professional service to an information business. Under health care reform, radiology will transition its emphasis from volume to greater value. Radiology's future brightens with the adoption of a philosophy of offering information rather than "reads" for decision making. Staunchly defending the status quo via turf wars is unlikely to constitute a

  12. Artificial insemination in pigs today.

    PubMed

    Knox, R V

    2016-01-01

    Use of artificial insemination (AI) for breeding pigs has been instrumental for facilitating global improvements in fertility, genetics, labor, and herd health. The establishment of AI centers for management of boars and production of semen has allowed for selection of boars for fertility and sperm production using in vitro and in vivo measures. Today, boars can be managed for production of 20 to 40 traditional AI doses containing 2.5 to 3.0 billion motile sperm in 75 to 100 mL of extender or 40 to 60 doses with 1.5 to 2.0 billion sperm in similar or reduced volumes for use in cervical or intrauterine AI. Regardless of the sperm dose, in liquid form, extenders are designed to sustain sperm fertility for 3 to 7 days. On farm, AI is the predominant form for commercial sow breeding and relies on manual detection of estrus with sows receiving two cervical or two intrauterine inseminations of the traditional or low sperm doses on each day detected in standing estrus. New approaches for increasing rates of genetic improvement through use of AI are aimed at methods to continue to lower the number of sperm in an AI dose and reducing the number of inseminations through use of a single, fixed-time AI after ovulation induction. Both approaches allow greater selection pressure for economically important swine traits in the sires and help extend the genetic advantages through AI on to more production farms. PMID:26253434

  13. Pattern formation today

    PubMed Central

    Chuong, Cheng-Ming; Richardson, Michael K.

    2010-01-01

    Patterns are orders embedded in randomness. They may appear as spatial arrangements or temporal series, and the elements may appear identical or with variations. Patterns exist in the physical world as well as in living systems. In the biological world, patterns can range from simple to complex, forming the basic building blocks of life. The process which generates this ordering in the biological world was termed pattern formation. Since Wolpert promoted this concept four decades ago, scientists from molecular biology, developmental biology, stem cell biology, tissue engineering, theoretical modeling and other disciplines have made remarkable progress towards understanding its mechanisms. It is time to review and re-integrate our understanding. Here, we explore the origin of pattern formation, how the genetic code is translated into biological form, and how complex phenotypes are selected over evolutionary time. We present four topics: Principles, Evolution, Development, and Stem Cells and Regeneration. We have interviewed several leaders in the field to gain insight into how their research and the field of pattern formation have shaped each other. We have learned that both molecular process and physico-chemical principles are important for biological pattern formation. New understanding will emerge through integration of the analytical approach of molecular-genetic manipulation and the systemic approach of model simulation. We regret that we could not include every major investigator in the field, but hope that this Special Issue of the Int. J. Dev. Biol. represents a sample of our knowledge of pattern formation today, which will help to stimulate more research on this fundamental process. PMID:19557673

    PubMed

    Woodward, Tony M

    2009-02-01

    Dental radiology is the core diagnostic modality of veterinary dentistry. Dental radiographs assist in detecting hidden painful pathology, estimating the severity of dental conditions, assessing treatment options, providing intraoperative guidance, and also serve to monitor success of prior treatments. Unfortunately, most professional veterinary training programs provide little or no training in veterinary dentistry in general or dental radiology in particular. Although a technical learning curve does exist, the techniques required for producing diagnostic films are not difficult to master. Regular use of dental x-rays will increase the amount of pathology detected, leading to healthier patients and happier clients who notice a difference in how their pet feels. This article covers equipment and materials needed to produce diagnostic intraoral dental films. A simplified guide for positioning will be presented, including a positioning "cheat sheet" to be placed next to the dental x-ray machine in the operatory. Additionally, digital dental radiograph systems will be described and trends for their future discussed. PMID:19410234

    2012-01-01

    With the increasing tempo of military conflicts in the last decade, much has been learnt about imaging battlefield casualties in the acute setting. Ultrasound in the form of focused abdominal sonography in trauma (FAST) has proven invaluable in emergency triage of patients for immediate surgery. Multidetector CT allows accurate determination of battlefield trauma injuries. It permits the surgeons and anaesthetists to plan their interventions more thoroughly and to be made aware of clinically occult injuries. There are common injury patterns associated with blast injury, gunshot wounds and blunt trauma. While this body of knowledge is most applicable to the battlefield, there are parallels with peacetime radiology, particularly in terrorist attacks and industrial accidents. This pictorial review is based on the experiences of a UK radiologist deployed in Afghanistan in 2010. PMID:22806621

We will cite the relative roles of mission and instrument data centers and resident archives, multi-mission data centers, and the growing importance of virtual discipline observatories and cross-cutting services including the evolution of a common data dictionary. We will briefly summarize our view of the most important challenges still faced by users and providers, and our vision in ow the efforts today can evolve into a more and more enabling data framework for the global research community to tap the widest range of existing missions and their data to address a full range of critical science questions from the scale of microphysics to the heliospheric system as a whole.

    The rapid advances in mobile computing technology have the potential to change the way radiology and medicine as a whole are practiced. Several mobile computing advances have not yet found application to the practice of radiology, while others have already been applied to radiology but are not in widespread clinical use. This review addresses several areas where radiology and medicine in general may benefit from adoption of the latest mobile computing technologies and speculates on potential future applications.

  19. Radiological Image Compression

    NASA Astrophysics Data System (ADS)

    Lo, Shih-Chung Benedict

    The movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve, and transmit the volume of digital images. Basic research into image data compression is necessary in order to move from a film-based department to an efficient digital -based department. Digital data compression technology consists of two types of compression technique: error-free and irreversible. Error -free image compression is desired; however, present techniques can only achieve compression ratio of from 1.5:1 to 3:1, depending upon the image characteristics. Irreversible image compression can achieve a much higher compression ratio; however, the image reconstructed from the compressed data shows some difference from the original image. This dissertation studies both error-free and irreversible image compression techniques. In particular, some modified error-free techniques have been tested and the recommended strategies for various radiological images are discussed. A full-frame bit-allocation irreversible compression technique has been derived. A total of 76 images which include CT head and body, and radiographs digitized to 2048 x 2048, 1024 x 1024, and 512 x 512 have been used to test this algorithm. The normalized mean -square-error (NMSE) on the difference image, defined as the difference between the original and the reconstructed image from a given compression ratio, is used as a global measurement on the quality of the reconstructed image. The NMSE's of total of 380 reconstructed and 380 difference images are measured and the results tabulated. Three complex compression methods are also suggested to compress images with special characteristics. Finally, various parameters which would effect the quality of the reconstructed images are discussed. A proposed hardware compression module is given in the last chapter.

    Current health care reform in the United States is producing a shift in radiology practice from the traditional volume-based role of performing and interpreting a large number of examinations to providing a more affordable and higher-quality service centered on patient outcomes, which is described as a value-based approach to the provision of health care services. In the 1990 s, evidence-based medicine was defined as the integration of current best evidence with clinical expertise and patient values. When these methods are applied outside internal medicine, the process is called evidence-based practice (EBP). EBP facilitates understanding, interpretation, and application of the best current evidence into radiology practice, which optimizes patient care. It has been incorporated into "Practice-based Learning and Improvement" and "Systems-based Practice," which are two of the six core resident competencies of the Accreditation Council for Graduate Medical Education and two of the 12 American Board of Radiology milestones for diagnostic radiology. Noninterpretive skills, such as systems-based practice, are also formally assessed in the "Quality and Safety" section of the American Board of Radiology Core and Certifying examinations. This article describes (a) the EBP framework, with particular focus on its relevance to the American Board of Radiology certification and maintenance of certification curricula; (b) how EBP can be integrated into a residency program; and (c) the current value and likely place of EBP in the radiology information technology infrastructure.

    A decade ago, incinerator ash was of little concern. There wasn't much of it, and it was treated like soil of fill and therefore disposed of without much concern. Today, however, the situation is far different. Waste-to-energy plants reduce the amount of trash they process by 90%, but they require environmentally sound landfills to dispose of residue. This paper examines the management of incinerator ash. At its best, incinerator ash is well burned out; at worst, it is more pyrolized and contains unburned carbon. This latter case is likely following receipt of rain-saturated waste at the incinerator. Ash contains about 15 to 20 weight of unburnables; for example metal cans, ceramics, other metals and so on. According to the author, recent work on presence of combustion products in the ash does not show appreciable levels of dioxins leaching form ash.

    A recent essay in CBE—Life Sciences Education criticized biology education researchers’ use of the term misconceptions and recommended that, in order to be up-to-date with education research, biology education researchers should use alternative terms for students’ incorrect ideas in science. We counter that criticism by reviewing the continued use and the meaning of misconceptions in education research today, and describe two key debates that account for the controversy surrounding the term. We then identify and describe two areas of research that have real implications for tomorrow's biology education research and biology instruction: 1) hypotheses about the structure of student knowledge (coherent vs. fragmented) that gives rise to misconceptions; and 2) the “warming trend” that considers the effects of students’ motivation, beliefs about the nature of knowledge and learning (their epistemic beliefs), and learning strategies (their cognitive and metacognitive skills) on their ability to change their misconceptions in science. We conclude with a description of proposed future work in biology education research related to misconceptions. PMID:26086651

    The Institute of Diagnostic Radiology at the Heinrich-Heine-University Duesseldorf has recently defined and implemented more than thirty organizational changes as a result of a quality control project. The aim was to improve quality and efficiency of the Radiology service. The project was carried out in cooperation with an external consulting firm. To date the positive impact of this project on our work has been so profound that we would like to communicate some of the results in form of this report. During the first phase of the project quality circles were formed to define the various quality criteria and aims of a good service. Today these represent the core of a new quality policy for the Institute. In a second phase all members of staff cooperatively developed precise plans of action for implementation of the necessary changes. Main achievements are the reduction of organizational and communicational deficits obstructing the work process, enhancement of interaction between junior and senior medical staff, upgrading of the role and field of action of the radiography staff and last but not least improvements of cooperation between secretarial and medical staff.

    In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications. Machine learning identifies complex patterns automatically and helps radiologists make intelligent decisions on radiology data such as conventional radiographs, CT, MRI, and PET images and radiology reports. In many applications, the performance of machine learning-based automatic detection and diagnosis systems has shown to be comparable to that of a well-trained and experienced radiologist. Technology development in machine learning and radiology will benefit from each other in the long run. Key contributions and common characteristics of machine learning techniques in radiology are discussed. We also discuss the problem of translating machine learning applications to the radiology clinical setting, including advantages and potential barriers. PMID:22465077

    N.L. Bowen pointed out that the effect of assimilating fusible rock into a cooling magma is to increase the volume of residual liquids, not change the cotectic relations that govern the compositions of those liquids. Accurate estimation of volumes of initial and residual liquids in evolving magmatic systems remains impossible, and petrologists interested in assimilation have tended to focus instead on identifying passive chemical tracers of crustal input into volcanic systems, especially during the last ~35 years in which high-quality trace element and isotope data have been available. Much of the motivation for these studies has arisen from the desire to use basaltic magmas as probes of mantle geochemistry, which relies on stripping from the basalt any chemical changes resulting from interaction between mantle-derived magma and crust. Despite the impressive array of high quality whole rock chemical data (typically concentrations of ~40 elements, and isotopic ratios from any or all of the systems Rb/Sr, Sm/Nd, U/Th/Pb, Lu/Hf, Re/Os, O and U/Th) applied to individual cases, two different investigators can interpret the same data set to arrive at highly disparate conclusions about the amount of crustal assimilation involved in the petrogenesis of, say, lavas from a continental volcanic field. In part, this situation arises from a decoupling between the sophistication of the chemical data and the naiveté with which we view processes of magma transport and storage. Two current developments promise to greatly improve our understanding of assimilation over the 25 years until the centenary celebrations of the publication of "The Evolution of the Igneous Rocks". First, models such as energy-constrained assimilation-fractional crystallization [1] that link a physical (in this case, thermodynamic) description of a magmatic system with the evolution of trace element abundances and isotopic ratios are revealing the wide range of results that arise from interaction of basaltic

    The zeitgeist of the new radiology workforce can best be described by a Bob Dylan song title: "The Times They Are A-Changin'." The new generation of physicians, although embracing the same foundations of medical practice as previous generations, places greater emphasis on personal satisfaction than its predecessors. Gone are the days when physicians operated as sole practitioners; today's workforce member is content to function in the role of "employee" in a trade-off for more lifestyle flexibility. This change has occurred not because of one specific factor but because of a change in the profession of medicine coupled with a combination of factors; familial responsibilities, avocational activities, and personal satisfaction have surfaced as motivating factors in choosing a profession. Today's workforce has a personal perception of success that may not be fulfilled solely by the contemporary practice of medicine. With the radiologist shortages that are now occurring and anticipated increased demand for staff radiologists, today's radiology workforce has helped shape the specialty into one that is altering its structure to attract and retain its workforce.

    Tablet computing and mobile resources are the hot topics in technology today, with that interest spilling into the medical field. To improve resident education, a fully configured iPad, referred to as the "Radiology Resident iPad Toolbox," was created and implemented at the University of Colorado. The goal was to create a portable device with comprehensive educational, clinical, and communication tools that would contain all necessary resources for an entire 4-year radiology residency. The device was distributed to a total of 34 radiology residents (8 first-year residents, 8 second-year residents, 9 third-year residents, and 9 fourth-year residents). This article describes the process used to develop and deploy the device, provides a distillation of useful applications and resources decided upon after extensive evaluation, and assesses the impact this device had on resident education. The Radiology Resident iPad Toolbox is a cost-effective, portable, educational instrument that has increased studying efficiency; improved access to study materials such as books, radiology cases, lectures, and web-based resources; and increased interactivity in educational conferences and lectures through the use of audience-response software, with questions geared toward the new ABR board format. This preconfigured tablet fully embraces the technology shift into mobile computing and represents a paradigm shift in educational strategy. PMID:23647869

    The diagnostic use of oral radiology is an essential part of daily dental practice. Due to the potentially harmful nature of ionising radiation, the clinical use of oral radiology in the Netherlands is framed by clinical practice guidelines and regulatory requirements. Undergraduate students receive intensive theoretical and practical training in practical and theoretical radiology, with the aim of obtaining the 'Eindtermen Stralingshygiëne voor Tandartsen en Orthodontisten'-certificate, which is required for legal permission to use oral radiology in dental practice. It is recommended that the curriculum be expanded to include the areas of knowledge required to qualify for the 'Eindtermen Stralingshygiëne voor het gebruik van CBCT-toestellen door tandartsen' (the certificate for the use of conebeam radiology by dentists). The general dental practitioner is faced with changing laws and regulations in all areas of practice. One of the most significant legal changes in the field of dental radiology was the introduction of the new radiation protection and safety rules in 2014. Moreover, a large group of dentists is also being confronted with the transition from conventional to digital images, with all its challenges and changes in everyday practice. PMID:27073811

    As the staffing shortage continues to impact radiology departments and outpatient imaging centers, managers look for ways to solve staffing issues internally. Lehigh Valley Hospital and Health Network investigated the feasibility of adding a position of radiology tech aide. This proposal was driven by a desire to improve retention of staff, improve employee satisfaction and reduce turnover. A 6-month pilot program was conducted at the network's highest-volume facility. One tech aide underwent extensive training and eventually began performing some of the tasks identified in the analysis. Each area within radiology worked with an intern to identify each step in its work process. Each step identified led to the question, "What happens if?" The workflow process provided a detailed look a the number of steps required for a technologist to perform a study from start to finish. In May 2002, the administrator submitted a project proposal to management engineering to evaluate radiologic technologists' workloads and identify tasks that could be performed by a tech aide. Activity-Based Management (ABM)--a process that emphasizes activities over resources--was utilized to study work activities. The analysis identified the appropriate tasks and revealed that 5 FTEs were needed to assist the technologists in all areas of radiology. A workflow was completed for each area within radiology. Some areas identified bottlenecks, which caused delays in the process and some redundant work for the staff. Data were presented to the network administration. Staffing realities, labor pool availability within the existing network staff, and detailed task identifications also were provided. A total of 5 FTE tech aides were approved. The final program included in-depth tech-aide training; effective and open communication between management and technologists; and a collaborative, education-oriented relationship between technologists and tech aides.

    Because of their typically small in-house computer and network staff, non-university hospitals often hesitate to consider picture archiving and communication system (PACS) as a solution to the very demanding financial, clinical, and technological needs of today's Radiology Department. This article presents the experiences of the 3-year process for the design and implementation of the Radiology Electronic Imaging Network (REIN) in the Department of Radiology at The Western Pennsylvania Hospital (WPH). WPH embarked on this project in late 1994 to find a solution to the very pressing demands to reduce operating costs and improve service to primary care clinicians, both on-site and at WPH-affiliated clinics. A five-member committee consisting of in-house medical, administrative, information services, and medical physics staff was formed to design a network that would satisfy specific needs of WPH by using a phased mini-PACS approach and to select the various vendors to implement it. Suppliers for individual mini-PACS were selected to provide modality-specific solutions. For the backbone network, vendors were evaluated based on their technological progress, competence and resources, the commitment of the company to the imaging network business, and their willingness to embark on a mid-sized PACS project such as this. Based on patient volume, workflow patterns, and image quality requirements, the committee produced proposals detailing number and location of workstations, short- and long-term memory requirements, and so on. Computed tomography/magnetic resonance imaging, computer radiography, ultrasound, nuclear medicine, digital fluoroscopy, and angiography mini-PACS have been implemented over the past 2 years, and most of these are already integrated into the main REIN. This article presents detailed information concerning the design, selection and implementation processes, including storage requirement calculations. This indicates that PACS implementation is achievable

  14. Successful Transformational Radiology Leaders.

    PubMed

    Douget, Karen

    2015-01-01

    Transformational radiology leaders elevate subordinates, expand self-awareness, develop lasting relationships, strive to exceed expectations, and uphold the vision and goals of the organization. In order for radiology leaders to become more transformational in their leadership style there are four fundamental elements they must learn: idealized influence, individualized consideration, inspirational motivation, and intellectual stimulation. Leaders can utilize personality and self-assessments to learn more about themselves, identify areas of strengths and weaknesses, and learn to be more effective when leading employees. PMID:26710553

  15. Passion in today's health care leaders.

    PubMed

    Piper, Llewellyn E

    2005-01-01

    Passion in today's health care leaders is essential as health care organizations face increasing demands for survival. Leaders in health care have been educated, selected, promoted, and retained based on their analytical and creativity skills. Today's health care leaders must also have emotional intelligence. Emotional intelligence is primal for passion. Emotional intelligence, which leads to passion, is crucial to the survivability of today's health care organizations. In order for health care organizations to go from good to great, the leader must inspire followers through passion. This article encourages health care leaders to gain awareness of emotional intelligence and to use emotional intelligence as part of their leadership to inspire passion. Through passion, leaders and followers become more motivated to accomplish the health care mission of serving others. PMID:15825818

  16. [Irreversible image compression in radiology. Current status].

    PubMed

    Pinto dos Santos, D; Jungmann, F; Friese, C; Düber, C; Mildenberger, P

    2013-03-01

    Due to increasing amounts of data in radiology methods for image compression appear both economically and technically interesting. Irreversible image compression allows markedly higher reduction of data volume in comparison with reversible compression algorithms but is, however, accompanied by a certain amount of mathematical and visual loss of information. Various national and international radiological societies have published recommendations for the use of irreversible image compression. The degree of acceptable compression varies across modalities and regions of interest.The DICOM standard supports JPEG, which achieves compression through tiling, DCT/DWT and quantization. Although mathematical loss due to rounding up errors and reduction of high frequency information occurs this results in relatively low visual degradation.It is still unclear where to implement irreversible compression in the radiological workflow as only few studies analyzed the impact of irreversible compression on specialized image postprocessing. As long as this is within the limits recommended by the German Radiological Society irreversible image compression could be implemented directly at the imaging modality as it would comply with § 28 of the roentgen act (RöV).

  17. Informatics in radiology: radiology gamuts ontology: differential diagnosis for the Semantic Web.

    PubMed

    Budovec, Joseph J; Lam, Cesar A; Kahn, Charles E

    2014-01-01

    The Semantic Web is an effort to add semantics, or "meaning," to empower automated searching and processing of Web-based information. The overarching goal of the Semantic Web is to enable users to more easily find, share, and combine information. Critical to this vision are knowledge models called ontologies, which define a set of concepts and formalize the relations between them. Ontologies have been developed to manage and exploit the large and rapidly growing volume of information in biomedical domains. In diagnostic radiology, lists of differential diagnoses of imaging observations, called gamuts, provide an important source of knowledge. The Radiology Gamuts Ontology (RGO) is a formal knowledge model of differential diagnoses in radiology that includes 1674 differential diagnoses, 19,017 terms, and 52,976 links between terms. Its knowledge is used to provide an interactive, freely available online reference of radiology gamuts ( www.gamuts.net ). A Web service allows its content to be discovered and consumed by other information systems. The RGO integrates radiologic knowledge with other biomedical ontologies as part of the Semantic Web.

  6. Ethical problems in radiology: radiological consumerism.

    PubMed

    Magnavita, N; Bergamaschi, A

    2009-10-01

    One of the causes of the increasing request for radiological examinations occurring in all economically developed countries is the active role played by the patient-consumer. Consumerism places the radiologist in an ethical dilemma, between the principle of autonomy on the one hand and the ethical principles of beneficence, nonmaleficence and justice on the other. The choice made by radiologists in moral dilemmas is inspired by an adherence to moral principles, which in Italy and elsewhere refer to the Judaeo-Christian tradition or to neo-Darwinian relativism. Whatever the choice, the radiologist is bound to adhere to that choice and to provide the patient with all the relevant information regarding his or her state of health. PMID:19662338

    2014-03-01

    The technical progress and broader indications for cross-sectional imaging continuously increase the number of radiological images to be assessed. However, as the amount of image information and available resources (radiologists) do not increase at the same pace and the standards of radiological interpretation and reporting remain consistently high, radiologists have to rely on computer-based support systems. Novel semantic technologies and software relying on structured ontological knowledge are able to "understand" text and image information and interconnect both. This allows complex database queries with both the input of text and image information to be accomplished. Furthermore, semantic software in combination with automatic detection and segmentation of organs and body regions facilitates personalized supportive information in topographical accordance and generates additional information, such as organ volumes. These technologies promise improvements in workflow; however, great efforts and close cooperation between developers and users still lie ahead. PMID:24522625

  17. Emerging strategic themes for guiding change in academic radiology departments.

    PubMed

    Chan, Stephen; Gunderman, Richard B

    2005-08-01

    Academic radiologists are faced with increasing demands on their time and energy, particularly in the clinical arena, where larger examination volumes and higher service expectations are the norm for most medical centers. These demands are intensified by the continuing shortage of academic radiologists. If academic radiology departments continue to devote most of their resources to the clinical mission at the expense of research and educational missions, then there are potentially serious adverse consequences for long-term viability of the profession of radiology. This dilemma represents a critical strategic problem, not just for academic radiology but also for the entire profession of radiology. In this article, the success and growth of academic radiology during the 20th century are framed as the result of the dogged pursuit of certain key strategic themes. With the concept of paradigm shift, introduced by Kuhn, several new strategic themes are identified that are just emerging from changes in work practices, organizational structure, and mind-sets in radiology departments at academic medical centers. One benefit of this approach is that it facilitates the ability of radiologists to articulate and focus on those strategic themes that will help academic radiology departments to adapt more rapidly and successfully to environmental changes during the 21st century.

    Imaging plays a key role in the management of conjoined twins. Pre-operative multi-modality studies are vital to assess operability and to aid surgical planning. Technical advances in imaging such as high-resolution isovolumetric magnetic resonance imaging (MRI) techniques and three-dimensional modeling now result in extremely accurate anatomical information. Varied information from a comprehensive radiological work-up enables the surgeons to plan the safest possible operative procedure, helps the anesthetic team before and during surgery, and guides the intensive care team in the post-operative phase. This article will review the radiological techniques used in our institution, highlighting potential pitfalls with the various imaging modalities. PMID:26382258

    Terror resulting from the use of a radiological dispersal device (RDD) relies upon an individual's lack of knowledge and understanding regarding its significance. Disabling this terror will depend upon realistic reviews of the current conservative radiation protection regulatory standards. It will also depend upon individuals being able to make their own informed decisions merging perceived risks with reality. Preparation in these areas will reduce the effectiveness of the RDD and may even reduce the possibility of its use.

    1995-05-01

    This report presents a comprehensive inventory of the radiological and nonradiological contaminants in waste buried or projected to be buried from 1984 through 2003 in the Subsurface Disposal Area (SDA) at the Radioactive Waste Management Complex (RWMC) of the Idaho National Engineering Laboratory. The project to compile the inventory is referred to as the recent and projected data task. The inventory was compiled primarily for use in a baseline risk assessment under the Comprehensive Environmental Response, Compensation, and Liability Act. The compiled information may also be useful for environmental remediation activities that might be necessary at the RWMC. The information that was compiled has been entered into a database termed CIDRA-the Contaminant Inventory Database for Risk Assessment. The inventory information was organized according to waste generator and divided into waste streams for each generator. The inventory is based on waste information that was available in facility operating records, technical and programmatic reports, shipping records, and waste generator forecasts. Additional information was obtained by reviewing the plant operations that originally generated the waste, by interviewing personnel formerly employed as operators, and by performing nuclear physics and engineering calculations. In addition to contaminant inventories, information was compiled on the physical and chemical characteristics and the packaging of the 99 waste streams. The inventory information for waste projected to be buried at the SDA in the future was obtained from waste generator forecasts. The completeness of the contaminant inventories was confirmed by comparing them against inventories in previous reports and in other databases, and against the list of contaminants detected in environmental monitoring performed at the RWMC.

  8. Motivation in a multigenerational radiologic science workplace.

    2008-01-01

    For the first time in history, radiologic science (RS) workplaces consist of 4 generational cohorts. As each cohort possess their own attitudes, values, work habits, and expectations, motivating a generational diverse workplace is challenging. Through the understanding of generational differences, managers are better able to accommodate individual as well as generational needs and help create a more productive and higher performing workplace. The purpose of this paper is to assist managers in the understanding and utilization of generational differences to effectively motivate staff in an RS workplace. Generational cohorts will be defined and discussed along with an in-depth discussion on each of the generations performing in today's RS workplace. Motivators and how they impact the different generational cohorts will be addressed along with how to best motivate a multigenerational RS workplace. PMID:18714760

  9. Risk communication and radiological/nuclear terrorism: a strategic view.

    PubMed

    Becker, Steven M

    2011-11-01

    It is now widely recognized that effective communication is a crucial element in radiological/nuclear terrorism preparedness. Whereas in the past, communication and information issues were sometimes viewed as secondary in comparison with technical concerns, today the need to improve risk communication, public information, and emergency messaging is seen as a high priority. The process of improving radiological/nuclear terrorism risk communication can be conceptualized as occurring in four overlapping phases. The first phase involves the recognition that communication and information issues will be pivotal in shaping how a radiological/nuclear terrorism incident unfolds and in determining its outcome. This recognition has helped shape the second phase, in which various research initiatives have been undertaken to provide an empirical basis for improved communication. In the third and most recent phase, government agencies, professional organizations and others have worked to translate research findings into better messages and informational materials. Like the first and second phases, the third phase is still unfolding. The fourth phase in risk communication for radiological/nuclear terrorism-a mature phase-is only now just beginning. Central to this phase is a developing understanding that for radiological/nuclear terrorism risk communication to be fully effective, it must go beyond crafting better messages and materials (as essential as that may be). This emerging fourth phase seeks to anchor radiological/nuclear communication in a broader approach: one that actively engages and partners with the public. In this article, each of the four stages is discussed, and future directions for improving radiological/nuclear terrorism risk communication are explored. PMID:21979539

  10. Technology in radiology: advances in diagnostic imaging & therapeutics.

    PubMed

    Stern, S M

    1993-01-01

    Nearly 100 years from its birth, radiology continues to grow as though still in adolescence. Although some radiologic technologies have matured more than others, new applications and techniques appear regularly in the literature. Radiology has evolved from purely diagnostic devices to interventional technologies. New contrast agents in MRI, X ray and ultrasound enable physicians to make diagnoses and plan therapies with greater precision than ever before. Techniques are less and less invasive. Advances in computer technology have given supercomputer-like power to high-end nuclear medicine and MRI systems. Imaging systems in most modalities are now designed with upgrades in mind instead of "planned obsolescence." Companies routinely upgrade software and other facets of their products, sometimes at no additional charge to existing customers. Hospitals, radiology groups and imaging centers will face increasing demands to justify what they do according to patient outcomes and management criteria. Did images make the diagnosis or confirm it? Did the images determine optimal treatment strategies or confirm which strategies might be appropriate? Third-party payers, especially the government, will view radiology in those terms. The diagnostic imaging and therapy systems of today require increasingly sophisticated technical support for maintenance and repair. Hospitals, radiology groups and imaging centers will have to determine the most economic and effective ways to guarantee equipment up-time. Borrowing from the automotive industry, some radiology manufacturers have devised transtelephonic software systems to facilitate remote troubleshooting. To ensure their fiscal viability, hospitals continue to acquire new imaging and therapy technologies for competitive and access-to-services reasons.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:10129808

    Objective: Increasing evidence indicates that the thalamus may be a location of early neurodegeneration in multiple sclerosis (MS). Our objective was to identify the presence of gray matter volume loss and thinning in patients with radiologically isolated syndrome (RIS). Methods: Sixty-three participants were included in this case-control study. Twenty-one patients with RIS were age- and sex-matched to 42 healthy controls in a 1:2 ratio. All participants underwent brain MRIs on a single 3T scanner. After lesion segmentation and inpainting, 1 mm3-isometric T1-weighted images were submitted to FreeSurfer (v5.2). Normalized cortical and deep gray matter volumes were compared between patients with RIS and controls using t tests, and thalamic volumes were correlated with white matter lesion volumes using Pearson correlation. Exploratory cortical thickness maps were created. Results: Although traditional normalized total gray and white matter volumes were not statistically different between patients with RIS and controls, normalized left (0.0046 ± 0.0005 vs 0.0049 ± 0.0004, p = 0.006), right (0.0045 ± 0.0005 vs 0.0048 ± 0.0004, p = 0.008), and mean (0.0045 ± 0.0005 vs 0.0049 ± 0.0004, p = 0.004) thalamic volumes were significantly lower in patients with RIS (n = 21, mean age 41.9 ± 12.7 years) than in controls (n = 42, mean age 41.4 ± 11.2 years). Thalamic volumes correlated modestly with white matter lesion volumes (range: r = −0.35 to −0.47). Conclusion: Our data provide novel evidence of thalamic atrophy in RIS and are consistent with previous reports in early MS stages. Thalamic volume loss is present early in CNS demyelinating disease and should be further investigated as a metric associated with neurodegeneration. PMID:25884012

    1985-12-01

    The last decade has been a period of astonishing growth and vigor for FT-IR spectroscopy. The first International Conference on Fourier Transform Spectroscopy held in Aspen, Colorado, in 1970, described new instrumentation using Michelson interferometers that had been developed in response to problems in astro-physics, where faster acquisition of data and better ways of handling the large quantity of data generated were needed. The problems had driven the development of new instrumentation. With this impetus, instrument manufacturers introduced reliable, computerized FT-IR instruments for use by industry. These new instru-ments, with their speed and advanced data processing capabilities, led to an explosion of new examples of practical problem solving, as well as new sophistication in analyzing structures of materials or composition mixtures. Today the field of industrial infrared spectroscopy which was literally "transformed" just 15 years ago is vigorous, healthy, and still expanding. Perhaps we have now come full circle, for today industry is again articulating ever more challenging problems that need solving via novel instrumentation and/or accessories. This will lead to a tomorrow in areas that have been elegantly described in the invited lectures and poster contributions of this conference. In this paper, we will describe some typical uses of FT-IR today and from them predict where FT-IR will "walk tomorrow". We will concentrate on industrial applications because that is the community we represent. It is also relevant to point out that the growth and success of new analytical tools or techniques are dependent on the extent of use by industry. Industrial practical problem solving - and just because it's practical or solving a problem does not preclude good science and basic work - drives the development of newer and better ways to get answers to problems or to understand properties of materials.

    At one time, sulfidation corrosion threatened to severely limit the use of gas turbines in marine applications, markedly reduce the life of industrial gas turbines, and affect the performance of aircraft engines. Today, gas turbine engines drive U.S. naval ships, produce electricity, and power aircraft. However, the problem of sulfidation corrosion has not disappeared. The rapid rate of degradation of airfoil materials in the presence of condensed sulfates is still a concern for gas turbine engines that operate in industrial and marine environments.

  16. Renewal of radiological equipment.

    PubMed

    2014-10-01

    In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imaging modalities and methods, the same progress speed resulted in accelerated technical and functional obsolescence of the same medical imaging equipment, consequently creating a need for renewal. Older equipment has a high risk of failures and breakdowns, which might cause delays in diagnosis and treatment of the patient, and safety problems both for the patient and the medical staff. The European Society of Radiology is promoting the use of up-to-date equipment, especially in the context of the EuroSafe Imaging Campaign, as the use of up-to-date equipment will improve quality and safety in medical imaging. Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or renewal. This plan should look forward a minimum of 5 years, with annual updates. Teaching points • Radiological equipment has a definite life cycle span, resulting in unavoidable breakdown and decrease or loss of image quality which renders equipment useless after a certain time period.• Equipment older than 10 years is no longer state-of-the art equipment and replacement is essential. Operating costs of older equipment will be high when compared with new equipment, and sometimes maintenance will be impossible if no spare parts are available.• Older equipment has a high risk of failure and breakdown, causing delays in diagnosis and treatment of the patient and safety problems both for the patient and the medical staff.• Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or replacement.

  2. Information surety for today and tomorrow

    SciTech Connect

    Fletcher, S.K.

    Information Surety is the enhancement of the confidentiality, integrity, and availability of information and software systems. It is attained through sequential steps: identification of software reliability requirements and information protection needs, designing for a balanced level of risk throughout the system, and application of appropriate software and hardware technologies and procedures. The ability to apply these steps when developing systems is impaired by a general lack of understanding of surety issues by system developers, and by the fact that there are many separate areas of knowledge involved that are not currently integrated into a disciplined approach (e.g., risk assessment, information access control in computers and networks, secure messaging, trusted software development). Our best systems today are achieved by clever designers who use ad-hoc methods. In the absence of good development tools, technologies may be applied haphazardly and/or retrofitted, without yielding balanced protection. This paper will take the audience through an exploration of the elements of information surety, some common misconceptions about information surety today, and the even greater challenges on the horizon. It will end with some suggestions for research areas which will help evolve the discipline of information surety.

    We developed a series of management reports to compare actual costs against expected costs for radiology departments on a more detailed level than previously available. We first developed labor standards for the most commonly employed diagnostic examinations and showed that increased patient complexity (resulting from, for example, immobility, precautions status, etc.) also increased the examination times up to 2.6-fold compared with the time required for average patients. Using labor standards and budgeted and actual volumes of average and complex patients, we calculated four types of variances: volume variance, examination mix variance, patient complexity variance, and technologist efficiency variance. Monitoring the technologist efficiency variance over time could be one key piece of information for improving departmental productivity. PMID:3923558

  4. Patient-centered Radiology.

    Patient-centered care (ie, care organized around the patient) is a model in which health care providers partner with patients and families to identify and satisfy patients' needs and preferences. In this model, providers respect patients' values and preferences, address their emotional and social needs, and involve them and their families in decision making. Radiologists have traditionally been characterized as "doctor-to-doctor" consultants who are distanced from patients and work within a culture that does not value patient centeredness. As medicine becomes more patient driven and the trajectory of health care is toward increasing patient self-reliance, radiologists must change the perception that they are merely consultants and become more active participants in patient care by embracing greater patient interaction. The traditional business model for radiology practices, which devalues interaction between patients and radiologists, must be transformed into a patient-centered model in which radiologists are reintegrated into direct patient care and imaging processes are reorganized around patients' needs and preferences. Expanding radiology's core assets to include direct patient care may be the most effective deterrent to the threat of commoditization. As the assault on the growth of Medicare spending continues, with medical imaging as a highly visible target, radiologists must adapt to the changing landscape by focusing on their most important consumer: the patient. This may yield substantial benefits in the form of improved quality and patient safety, reduced costs, higher-value care, improved patient outcomes, and greater patient and provider satisfaction.

    Quantum computers, string theory, holographic universes - to the general audience, today's physics can be as mystifying as it is fascinating. But modern ideas evolved from an earlier phase of physics - Newtonian mechanics, simple cause and effect - that is in principle easier for the non-expert to grasp. I have found that writing about physics from a historical and biographical perspective is an effective way to convey modern thinking by explaining where it comes from - it is a way of carrying the reader from concepts that make intuitive sense to ideas that seem, on first encounter, utterly bizarre. Smuggling explanations into stories satisfies the reader's desire for narrative - bearing in mind that narrative can include the evolution of ideas as well as tales about intriguing and original people.

    The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. PMID:24267935

It is pointed out that to secure a concrete foundation for the basic theory as well as astrophysical applications for black hole physics, it is essential to gain a suitable insight into these questions. In particular, we discuss the recent results investigating the final fate of a massive star within the framework of the Einstein gravity, and the stability and genericity aspects of the gravitational collapse outcomes in terms of black holes and naked singularities. Recent developments such as spinning up a black hole by throwing matter into it, and physical effects near naked singularities are considered. It is pointed out that some of the new results obtained in recent years in the theory of gravitational collapse imply interesting possibilities and understanding for the theoretical advances in gravity as well as towards new astrophysical applications.

The length of judges' assignments to this court varies as does the extent of their specialization. These courts differ from one another in numerous ways such as the minimum and maximum ages of their delinquency jurisdictions, the types of cases they are authorized to hear in addition to delinquency and child abuse and neglect, the extent to which referees or quasi-judicial hearing officers hear cases, whether or not the juvenile probation department is administered by the court, and the individual practices that constitute particular court cultures.

    In a statistical sample of 500 unwanted pregnancies surprisingly the share of women whose partners used a condom was not higher than the share of IUP-users (considering the relative frequency of use of both methods). This result was the motivation to investigate once more the use of the condom. After a short description of the history, the production, and the testing methods a discussion follows of the frequency of its use. In many countries the frequency of using the condom lies between that of hormonal oral contraceptives and the IUP. Today the reliability of the condom is higher than described in medical textbooks. In statistics of the seventies the failure rate is no more than 3 unwanted pregnancies in 100 years of usage. Harmful side effects or contraindications are not known. Therefore in cases of incompatibility or refusion of hormonal oral contraceptives reflections of the doctor on useful alternative methods of contraception should include the recommendation of the condom.

The altimetry data of ~500 series throughout the basin are used to determine rating curves that enable to tune the model parameters such as the depth and slope of small contributors still un-monitored, or the variations in Manning coefficient; and to make discharge series exceeding the time window of the model runs. With this case study, we show that the measurements collected today by conventional altimetry missions can be used to prepare SWOT in two directions: get geophysical values that will be necessary for the discharge algorithms of SWOT and compute discharge time series which will constitute an archive to be continued by SWOT.

    Background Global public health today faces new challenges and is impacted by a range of actors from within and outside state boundaries. The diversity of the actors involved has created challenges and a complex environment that requires a new context-tailored global approach. The World Federation of Public Health Associations has embarked on a collaborative consultation with the World Health Organization to encourage a debate on how to adapt public health to its future role in global health. Design A qualitative study was undertaken. High-level stakeholders from leading universities, multilateral organizations, and other institutions worldwide participated in the study. Inductive content analyses were performed. Results Stakeholders underscored that global public health today should tackle the political, commercial, economic, social, and environmental determinants of health and social inequalities. A multisectoral and holistic approach should be guaranteed, engaging public health in broad dialogues and a concerted decision-making process. The connection between neoliberal ideology and public health reforms should be taken into account. The WHO must show leadership and play a supervising and technical role. More and better data are required across many programmatic areas of public health. Resources should be allocated in a sustainable and accountable way. Public health professionals need new skills that should be provided by a collaborative global education system. A common framework context-tailored to influence governments has been evaluated as useful. Conclusions The study highlighted some of the main public health challenges currently under debate in the global arena, providing interesting ideas. A more inclusive integrated vision of global health in its complexity, shared and advocated for by all stakeholders involved in decision-making processes, is crucial. This vision represents the first step in innovating public health at the global level and should lead

    Measuring terrestrial gamma radiation from airborne platforms has proved to be a useful method for characterizing radiation levels over large areas. Over 300 aerial radiological surveys have been carried out over the past 25 years including U.S. Department of Energy (DOE) sites, commercial nuclear power plants, Formerly Utilized Sites Remedial Action Program/Uranium Mine Tailing Remedial Action Program (FUSRAP/UMTRAP) sites, nuclear weapons test sites, contaminated industrial areas, and nuclear accident sites. This paper describes the aerial measurement technology currently in use by the Remote Sensing Laboratory (RSL) for routine environmental surveys and emergency response activities. Equipment, data-collection and -analysis methods, and examples of survey results are described.

    Following the end of the Cold War, the mission of Rocky Flats Environmental Technology Site changed from production of nuclear weapons to cleanup. Authorization baseis documents for the facilities, primarily the Final Safety Analysis Reports, are being replaced with new ones in which accident scenarios are sorted into coarse bins of consequence and frequency, similar to the approach of DOE-STD-3011-94. Because this binning does not require high precision, a standardized approach for radiological dose evaluations is taken for all the facilities at the site. This is done through a standard calculation ``template`` for use by all safety analysts preparing the new documents. This report describes this template and its use.

    The use of mobile devices is revolutionizing the way we communicate, interact, are entertained, and organize our lives. With healthcare in general and radiology in particular becoming increasingly digital, the use of such devices in radiologic practice is inevitable. This article reviews the current status of the use of mobile devices in the clinical practice of radiology, namely in emergency teleradiology. Technical parameters such as luminance and resolution are discussed. The article also discusses the benefits of such mobility vis-à-vis the current limitations of the technologies available.

    Rapid growth in the amount of data that is electronically recorded as part of routine clinical operations has generated great interest in the use of Big Data methodologies to address clinical and research questions. These methods can efficiently analyze and deliver insights from high-volume, high-variety, and high-growth rate datasets generated across the continuum of care, thereby forgoing the time, cost, and effort of more focused and controlled hypothesis-driven research. By virtue of an existing robust information technology infrastructure and years of archived digital data, radiology departments are particularly well positioned to take advantage of emerging Big Data techniques. In this review, we describe four areas in which Big Data is poised to have an immediate impact on radiology practice, research, and operations. In addition, we provide an overview of the Big Data adoption cycle and describe how academic radiology departments can promote Big Data development. PMID:26683510

    The RadRelay effort developed small, field appropriate, portable prototype devices that allow radiological spectra to be downloaded from field radiological detectors, like the identiFINDER-U, and transmitted to land based experts. This communications capability was designed for the U. S. Coast Guard (USCG) but is also applicable to the Customs and Border Protection (CBP) personnel working in remote locations. USCG Level II personnel currently use the identiFINDER-U Hand-Held Radioisotope ID Devices (HHRIID) to detect radiological materials during specific boarding operations. These devices will detect not only radiological emissions but will also evaluate those emissions against a table of known radiological spectra. The RadRelay has been developed to significantly improve the functionality of HHRIID, by providing the capability to download radiological spectra and then transmit them using satellite or cell phone technology. This remote wireless data transfer reduces the current lengthy delay often encountered between the shipboard detection of unknown radiological material and the evaluation of that data by technical and command personnel. That delay is reduced from hours to minutes and allows the field located personnel to remain on station during the inspection and evaluation process.

    Medical imaging and interventional radiology sustained prompt changes in the last few years, mainly as a result of technology breakthroughs, rise in workload, deficit in workforce and globalization. Risk is considered to be the chance or possibility of incurring loss or of a negative event happening that may cause injury to patients or medical practitioners. There are various causes of risks leading to harm and injury in radiology departments, and it is one of the objectives of this paper to scrutinize some of the causes. This will drive to consideration of some of the approaches that are used in managing risks in radiology. This paper aims at investigating risk management in radiology, and this will be achieved through a thorough assessment of the risk control measures that are used in the radiology department. It has been observed that the major focus of risk management in such medical setting is to reduce and eliminate harm and injury to patients through integration of various medical precautions. The field of Radiology is rapidly evolving due to technology advances and the globalization of healthcare. This ongoing development will have a great impact on the level of quality of care and service delivery. Thus, risk management in radiology is essential in protecting the patients, radiologists, and the medical organization in terms of capital and widening of the reputation of the medical organization with the patients.

    The freeze-drying process and equipment have been improved over the years; the cycle times have shortened and the dried products have improved as a result. This talk will deal with these improvements and how we have progressed from the early systems to where we are today. Such areas of discussion will include: vacuum pumping systems, how they are sized and designed to meet the needs for general and special applications; heat transfer systems, and their use in maintaining the drying profile; condensing surface design, and what is best for certain types of dryers; controls and instrumentation, and how these have played a big part in the drying process and have made it possible to get repeatability; refrigeration systems, and the part they play in the performance of freeze-drying; and lastly the effect of internal stoppering, bottomless trays, and other items such as these have had on the present state of the art. It goes without saying that there have been many changes and there will continue to be changes and we shall endeavor to look into the future--as to what might well bo some of these changes.

    Two points in our recent article on Edward Teller's scientific life (Physics Today, August 2004, page 45) require correction. In our description of Teller's students, we incorrectly stated that Arthur Kantrowitz's thesis was on the generation of hypersonic molecular beams. Actually, his thesis was on heat capacity lags in gas dynamics. Kantrowitz's invention of high intensity sources for molecular beams came later in his career. Maurice Goldhaber has emphasized that the situation with respect to possible nuclear resonances in ({gamma},n) or ({gamma},fission) reactions was quite unclear at the time of George C. Baldwin and G. Stanley Klaiber's papers on these reactions. This was because the rapid rise of their yield to a prominent peak with increasing energy, followed by a slower fall off was then thought to have been due to the competition between the rapidly rising density of nuclear states and the eventual domination of other reaction channels at higher energies. Goldhaber realized, however, that there could be an analogy between a possible collective nuclear resonance and the restrahl resonance (essentially the transverse optical phonon mode) in polar crystals. Goldhaber sought out Teller because of his paper with Russell Lyddane and Robert Sachs, relating the restrahl frequency to the asymptotic behavior of the crystal's dielectric function. Goldhaber and Teller, in their paper together, went on to predict universal, giant photo-nuclear resonances.

  11. Tetralogy of fallot: yesterday and today.

    PubMed

    Starr, Joanne P

    Tetralogy of Fallot (TOF) is a cyanotic congenital cardiac defect that was first described by Stenson in 1672 and later named for Fallot, who in 1888 described it as a single pathological process responsible for (1) pulmonary outflow tract obstruction, (2) ventricular septal defect (VSD), (3) overriding aortic root, and (4) right ventricular hypertrophy. The surgical history of TOF began with the development of the systemic to pulmonary artery shunt (BT shunt) by Blalock, Taussig, and Thomas in 1944. Ten years later complete repair of TOF was performed by Lillehei using cross-circulation and by Kirklin with a primitive cardiopulmonary bypass circuit. Notable contributions by several other surgeons including Bahnson, Ebert, Malm, Trusler, Barratt-Boyes, and Castaneda would lead us into the modern era of surgery. Today, complete repair of TOF is performed before six months of age with low mortality (<2%). In select cases a modified version of the BT shunt is still performed as the initial procedure. Long-term survival rates are excellent (85%-90%). Adult survivors with TOF are an ever-increasing population and may require reintervention, surgically or catheter based. Promising future innovations include percutaneous pulmonary valve replacement, tissue-engineered autologous valves and conduits, and genetic manipulation. This article presents a review of TOF, including the history of surgical treatment, present-day approaches, and long-term outcomes. PMID:20091166

    With its focus on the quantity of production, often to the exclusion of other goals, today's food system is on an unsustainable course. The problem begins with and is driven by industrialized production of both crops and animals. Industrialization is a product of technological change, public policy, and, most recently, globalized trade. The lack of sustainability derives from reliance on the intensive use of nonrenewable and hard-to-renew resources-soil, antibiotics, fresh water, and fossil fuels, for example-but also from the waste and pollution created by the industrial model. For at least 50 years, American agriculture policies have promoted production of, and ultimately lower market prices for, commodity crops like corn, wheat, and soybeans. Over the last 3 decades in particular, these "cheap food" policies have exacerbated the negative impacts of an industrialized agriculture on the health of the agro-ecosystem, as well as on the health of the humans who must share and be sustained by it. Sustainability and health are two sides of the same food system coin. Policies that put US food production on more sustainable footing can help aid in public efforts to address the myriad crises confronting both the food and health systems. PMID:23173026

    Radiology has changed significantly in recent years. The volume of work has increased dramatically as has its complexity. Future radiologists need an adequate training and expertise in conventional practice as well as new techniques. This comes at a time when other stakeholders outside of radiology are voicing their own concerns. The rightly justified increasing focus on patient safety has placed even more emphasis on the demonstration of competent practice by all health care professionals. Credentialing has been put forward as a way to ensure a doctor is competent in specific areas. Credentialing may be an alien concept to many radiology trainees but moves are afoot in the United Kingdom to bring it to the forefront of its postgraduate medical training. Credentialing began in 20th century North America where it was linked to the process of privileging. It subsequently garnered a strong patient safety focus and has become a part of the international healthcare agenda. Not everyone agrees with credentialing, it has many criticisms including the risk of speciality “turf wars” and the stifling of medical excellence to name just a couple. Is credentialing in radiology here to stay or will it pass by quietly?

    Even prior to the introduction of criteria defining the radiologically isolated syndrome (RIS), longitudinal clinical data from individuals with incidentally identified T2 lesions suggestive of multiple sclerosis (MS) were described. Healthy individuals who do not exhibit signs of neurological dysfunction may have a brain MRI performed for a reason other than suspicion of MS that reveals unexpected anomalies highly suggestive of demyelinating plaques given their size, location, and morphology. These healthy subjects lack a history or symptomatology suggestive of MS and fulfill formal criteria for RIS, a recently described MS subtype that shares the phenotype of at-risk individuals for future demyelinating events. A formal description of RIS was first introduced in 2009 by Okuda et al., and defines a cohort of individuals who are at risk for future demyelinating events. European or North American observational studies have found that up to 30-45% of patients presenting with RIS will present with neurological symptoms, either acute or progressive. The median time to clinical conversion differs between studies. It was 2.3 years for a series of French patients and 5.4 years for an American cohort. Most patients who developed clinical symptoms had prior radiological progression. The presence of asymptomatic lesions in the cervical cord indicated an increased risk of progression, either to relapsing or to progressive MS. The consortium studying the epidemiology of RIS worldwide (RISC) presented their first retrospective cohort last year. Data were available for 451 RIS subjects (F: 354 [78.5%]). The mean age at RIS diagnosis was 37.2 years with a mean clinical follow-up time of 4.4 years. The observed 5-year conversion rate to the first clinical event was 34%. Of the converters within this time period, 9.6% fulfilled criteria for primary progressive MS. In the multivariate model, age, sex (male), and lesions within the cervical or thoracic spinal cord were identified as

    Radiology departments are a rich source of information in the form of digital radiology reports and images obtained in patients with a wide spectrum of clinical conditions. A free text radiology report and image search application known as Render was created to allow users to find pertinent cases for a variety of purposes. Render is a radiology report and image repository that pools researchable information derived from multiple systems in near real time with use of (a) Health Level 7 links for radiology information system data, (b) periodic file transfers from the picture archiving and communication system, and (c) the results of natural language processing (NLP) analysis. Users can perform more structured and detailed searches with this application by combining different imaging and patient characteristics such as examination number; patient age, gender, and medical record number; and imaging modality. Use of NLP analysis allows a more effective search for reports with positive findings, resulting in the retrieval of more cases and terms having greater relevance. From the retrieved results, users can save images, bookmark examinations, and navigate to an external search engine such as Google. Render has applications in the fields of radiology education, research, and clinical decision support. PMID:19564253

    Self-citation, considered as the number of times a paper cites other papers in the same journal, is an important criteria of journal quality. Our objective is to evaluate the self-citation in the official journal of the Spanish Society of Radiology (Radiología), and to compare it with the European Radiology and Radiology journals. Papers published in Radiología, European Radiology, and Radiology during 1997 and 1998 were analyzed. The Self Citation Index, considered as the ratio between self-references and total number of references per article, for the journals Radiología (SCIR), European Radiology (SCIER), and Radiology (SCIRY), were obtained and expressed as percentages. Also, the number of references to Radiología in European Radiology and Radiology papers were calculated. Stratification of the index per thematic area and article type was also performed. Mean SCIR, SCIER, and SCIRY values were compared with the ANOVA and the Student-Newman-Keuls tests. The self-citation index was statistically higher in Radiology (23.2%; p<0.0001) than in Radiología (1.8%) and European Radiology (0.8%). There were no statistically significant differences between SCIR and SCIER indexes ( p=0.25). In the stratification per thematic areas and article type, self-citation in Radiology was statistically higher ( p<0.0001), with the only exception of "Radioprotection" area ( p=0.2), to SCIR and SCIER. Although there were no statistically significant differences, by thematic areas SCIR was always larger than SCIER, with the only exception of the "Genitourinary imaging" area, and by article type SCIR also went greater to SCIER, except in review articles. Radiología, The Spanish official radiological journal, although not included in Index Medicus and its database Medline, had a larger number of self-citing than European Radiology in the period 1997-1998.

    Brown, Anthony H D

    Charles Darwin began The Origin of Species with a chapter entitled variation under domestication, which encapsulated decades of his research on a diverse array of animal and plant domesticated species. Variation in these species compared with that in their wild relatives, their origins and their selection by humans, formed a paradigm for his theory of the evolutionary origin of species by means of natural selection. This chapter, its subsequent expansion into a two-volume monograph, together with the rediscovery of Mendel's laws, later became the foundation of scientific plant breeding. In the period up to the present, several advances in genetics (such as artificial mutation, polyploidy, adaptation and genetic markers) have amplified the discipline with concepts and questions, the seeds of which are in Darwin's original words. Today, we are witnessing a flowering of genomic research into the process of domestication itself, particularly the specific major and minor genes involved. In one striking way, our view of domestic diversity contrasts with that in Darwin's writing. He stressed the abundance of diversity and the diversifying power of artificial selection, whereas we are concerned about dwindling genetic diversity that attends modern agriculture and development. In this context, it is paramount to strive for a deeper understanding of how farmer selection including both deliberate selection and unconscious selection, might generate and retain diversity. This knowledge is essential for devising in situ conservation measures. PMID:20643742

    Barrett, Patrick; Butler, Mary; Hale, Beatrice

    2016-01-01

    The abstract consideration of ethical questions in family and informal caregiving might rightly be criticized for ignoring the lived experience of people. This chapter seeks to avoid such oversight by reflecting on ethical issues in family care in a way that is based on careful social scientific inquiry into the well-being of caregivers. The chapter draws on our research and experience in working with family caregivers, both professionally and personally. We step back from a practical concern with policies to support the well-being of caregivers to consider ethical issues associated with their typically hidden role. The chapter begins by noting the growing reliance on family care today. It proceeds to outline the dynamic experience of moving into and out of the caregiver role, before discussing key ethical issues associated with family care. Many of these stem from the risk that caregivers can come to share in the reduced circumstances and vulnerability of those for whom they care. Critical ethical issues are related to the typically "unboundaried" responsibility of family caregivers for the well-being of the cared-for person, something that can be contrasted with the more boundaried and intermittent responsibility of formal caregivers. Additionally, all too often, family caregivers encounter situations where their responsibilities exceed their capacities, but where a choice to not provide care will result in harm to the cared-for person. In discussing these issues, this chapter seeks to make the case for developing more responsive forms of support that promote positive benefits for both caregivers and care recipients. PMID:26673377

    This patent application discloses a radiological measuring instrument including an angularly variable radiation-sensitive structure comprised of two blocks of material having a different index of refraction with one of the materials comprising a radiochromic substance whose refractive index changes through anomolous dispersion as a result of being exposed to radiation. The ratio of the two indices of refraction is selected to be close to unity, with the radiation-sensitive structure being pivotally adjusted so that light is directed into one end of the block comprising the material having the greater index of refraction. This element, moreover, is selected to be clear and transparent with the incident angle being close to the critical angle where total reflection of all incident light occurs. A portion of the incident light is furthermore projected through the clear transparent block without reflection, with the two beams emerging from the other end of the block, where they are detected. Exposure to radiation changes the index of refraction of the radiochromic block and accordingly the reflected energy emerging therefrom. Calibrated readjustment of the angle of incidence provides a measure of the sensed radiation.

    Radiology is among the medical disciplines which require the highest investment costs in the healthcare system. The need to design efficient workflows to ensure maximum utilization of the equipment has long been known. In order to be able to establish a sound financial plan prior to a project or equipment purchase, the costs of an examination have to be broken down by modality and compared with the reimbursement rates. Obviously, the same holds true for operative decisions when scarce human resources have to be allocated. It is the task of controlling to review the economic viability of the different modalities and ideally, the results are incorporated into the management decision-making processes. The main section of this article looks at the recognition and allocation of direct and indirect costs in a medical center (Medizinisches Versorgungszentrum - MVZ) in the German North Rhine region. The profit contribution of each examination is determined by deducting the costs from the income generated by the treatment of patients with either private or statutory health insurance.

    The new standard for radiology reporting templates being developed through the Integrating the Healthcare Enterprise (IHE) and DICOM organizations defines the storage and exchange of reporting templates as Hypertext Markup Language version 5 (HTML5) documents. The use of HTML5 enables the incorporation of "dynamic HTML," in which documents can be altered in response to their content. HTML5 documents can employ JavaScript, the HTML Document Object Model (DOM), and external web services to create intelligent reporting templates. Several reporting templates were created to demonstrate the use of scripts to perform in-template calculations and decision support. For example, a template for adrenal CT was created to compute contrast washout percentage from input values of precontrast, dynamic postcontrast, and delayed adrenal nodule attenuation values; the washout value can used to classify an adrenal nodule as a benign cortical adenoma. Dynamic templates were developed to compute volumes and apply diagnostic criteria, such as those for determination of internal carotid artery stenosis. Although reporting systems need not use a web browser to render the templates or their contents, the use of JavaScript creates innumerable opportunities to construct highly sophisticated HTML5 reporting templates. This report demonstrates the ability to incorporate dynamic content to enhance the use of radiology reporting templates.

    This report describes the findings from a literature review conducted as part of a Department of Energy, Office of Technology Development Biomass Remediation Task. The principal objective of this project is to develop a process or group of processes to treat radiologically contaminated vegetation in a manner that minimizes handling, processing, and treatment costs. Contaminated, woody vegetation growing on waste sites at SRS poses a problem to waste site closure technologies that are being considered for these sites. It is feared that large sections of woody vegetation (logs) can not be buried in waste sites where isolation of waste is accomplished by capping the site. Logs or large piles of woody debris have the potential of decaying and leaving voids under the cap. This could lead to cap failure and entrance of water into the waste. Large solid objects could also interfere with treatments like in situ mixing of soil with grout or other materials to encapsulate the contaminated sediments and soils in the waste sites. Optimal disposal of the wood includes considerations of volume reduction, treatment of the radioactive residue resulting from volume reduction, or confinement without volume reduction. Volume reduction consists primarily of removing the carbon, oxygen, and hydrogen in the wood, leaving an ash that would contain most of the contamination. The only contaminant that would be released by volume reduction would by small amounts of the radioactive isotope of hydrogen, tritium. The following sections will describe the waste sites at SRS which contain contaminated vegetation and are potential candidates for the technology developed under this proposal. The description will provide a context for the magnitude of the problem and the logistics of the alternative solutions that are evaluated later in the review. 76 refs.

  5. DOE standard: Radiological control

    1999-07-01

    The Department of Energy (DOE) has developed this Standard to assist line managers in meeting their responsibilities for implementing occupational radiological control programs. DOE has established regulatory requirements for occupational radiation protection in Title 10 of the Code of Federal Regulations, Part 835 (10 CFR 835), ``Occupational Radiation Protection``. Failure to comply with these requirements may lead to appropriate enforcement actions as authorized under the Price Anderson Act Amendments (PAAA). While this Standard does not establish requirements, it does restate, paraphrase, or cite many (but not all) of the requirements of 10 CFR 835 and related documents (e.g., occupational safety and health, hazardous materials transportation, and environmental protection standards). Because of the wide range of activities undertaken by DOE and the varying requirements affecting these activities, DOE does not believe that it would be practical or useful to identify and reproduce the entire range of health and safety requirements in this Standard and therefore has not done so. In all cases, DOE cautions the user to review any underlying regulatory and contractual requirements and the primary guidance documents in their original context to ensure that the site program is adequate to ensure continuing compliance with the applicable requirements. To assist its operating entities in achieving and maintaining compliance with the requirements of 10 CFR 835, DOE has established its primary regulatory guidance in the DOE G 441.1 series of Guides. This Standard supplements the DOE G 441.1 series of Guides and serves as a secondary source of guidance for achieving compliance with 10 CFR 835.

    A posthepatitic cirrhotic patient may undergo elective or urgent abdominal operation for an extra-hepatic or hepatic disease. According to the high postoperative morbidity (61%), surgery is indicated only for symptomatic or complicated cholelithiasis. A surgical procedure for refractory ascites has been devised to create a permanent peritoneo-venous shunt by a one way pressure-sensitive valve (Leveen). The procedure is simple and brings a long lasting relief with recovery in strength and nutrition and improved kidney function. Sclerotherapy is widely used to treat acute variceal bleeding while repeated sclerotherapy is used in the long-term management to eradicate varices. When indicated, liver transplantation is the best treatment to prevent variceal bleeding recurrence. Also portosystemic shunts effectively prevent recurrent variceal bleeding. They are, however, major operations with an important morbidity and mortality, particularly in poor risk patients. The most advocated shunts today are the Warren distal splenorenal shunt and the Sarfeh portacaval shunt using a small diameter prosthetic H-graft. The transjugular intrahepatic portosystemic stent-shunt (TIPSS) is a new treatment for portal hypertension and its complications. From a haemodynamic point of view it allows balanced hepatic perfusion. Postoperative mortality is rare; further bleeding and encephalopathy are reasonably acceptable. The most relevant complications concern dislocation of the prosthesis, stenosis and thrombosis of the shunt, which can be corrected by non-invasive dilatation. Encephalopathy is the main complication of surgical portosystemic shunts. It is usually controlled by protein diet restriction, and administration of lactulose or oral antibiotics. In severe forms the patients may be treated by an oesophageal transection with oesophagogastric devascularization, and by a postoperative suppression of the portosystemic shunt using external maneuvers.

    The Feed Materials Production Center was constructed to produce high purity uranium metal for use at various Department of Energy facilities. The waste products from these operations include general uncontaminated scrap and refuse, contaminated and uncontaminated metal scrap, waste oils, low-level radioactive waste, co-contaminated wastes, mixed waste, toxic waste, sludges from water treatment, and fly ash from the steam plant. This material is estimated to total more than 350,000 cubic meters. Other wastes stored in this area include laboratory chemicals and other combustible materials in the burn pit; fine waste stream sediments in the clear well; fly ash and waste oils in the two fly ash areas; lime-alum sludges and boiler plant blowdown in the lime sludge ponds; and nonradioactive sanitary waste, construction rubble, and asbestos in the sanitary landfill. A systematic survey of the surface soils throughout the Waste Storage Area, associated on-site drainages, and the fly ash piles was conducted using a Field Instrument for Detecting Low-Energy Radiation (FIDLER). Uranium is the most prevalent radioactive element in surface soil; U-238 is the principal radionuclide, ranging from 2.2 to 1790 pCi/g in the general Waste Storage Area. The maximum values for the next highest activity concentrations in the same area were 972 pCi/g for Th-230 and 298 pCi/g for U-234. Elevated activity concentrations of Th-230 were found along the K-65 slurry line, the maximum at 3010 pCi/g. U-238 had the highest value of 761 pCi/g in the drainage just south of pit no. 5. The upper fly ash area had the highest radionuclide activity concentrations in the surface soils with the maximum values for U-238 at 8600 pCi/g, U-235 at 2190 pCi/g, U-234 at 11,400 pCi/g, Tc-99 at 594 pCi/g, Ra-226 at 279 pCi/g, and Th-230 at 164 pCi/g.

    Each facility is tasked with maintaining personnel radiation exposure as low as reasonably achievable (ALARA). A continued effort is required to meet this goal by developing and implementing improvements to technical work documents (TWDs) and work performance. A review of selected TWDs from most facilities shows there is a need to incorporate more radiological control requirements into the TWD. The Radioactive Work Permit (RWP) provides a mechanism to place some of the requirements but does not provide all the information needed by the worker as he/she is accomplishing the steps of the TWD. Requiring the engineers, planners and procedure writers to put the radiological control requirements in the work steps would be very easy if all personnel had a strong background in radiological work planning and radiological controls. Unfortunately, many of these personnel do not have the background necessary to include these requirements without assistance by the Radiological Control organization at each facility. In addition, there seems to be confusion as to what should be and what should not be included in the TWD.

    Traditionally, radiologists have collected and saved interesting cases in their film formats to teach medical students, residents, and physicians. These cases are classified according to various coding schemes, although current schemes alone are insufficient to meet today's educational needs. Teaching methods and cases also vary among institutions, along with the manner in which instructors present information to their students. In order to address this problem, the authors developed a standardized radiology teaching knowledge database known as the Digital Radiology Image Learning Library (DRILL). DRILL is a relational image knowledge database providing access to standard mammography cases in digital image format along with a pool of clinical and radiological information on a per-case basis. The development platform chosen is a standard Apple Macintosh-II computer and the Oracle database environment. The data entry and query interfaces are implemented in HyperCard. Images are stored on magnetic disk but could be stored on optical media. Since the personal computer platform was chosen, a wide variety of course building tools are available through which a teacher can construct a course, such as authoring and multi-media systems for building computer based courses, or word processors for writing course outlines tests. The interface also provides image conversion tools which convert images into PC-compatible formats.

    As a part of the preparedness and response to possible radiological terror events, it is important to model the evolution of the radioactive cloud immediately after its formation, as a function of time, explosive quantity and local meteorological conditions. One of the major outputs of a cloud rise models is the evaluation of cloud top height, which is an essential input for most of the succeeding atmospheric dispersion models. This parameter strongly affects the radiological consequences of the event. Most of the cloud rise models used today, have been developed according to experiments were large quantities of explosives were used, within the range of hundreds of kilograms of TNT. The majority of these models, however, fail to address Radiological Dispersion Devices (RDD) events, which are typically characterized by smaller amounts of TNT. In this paper, a new, semi-empirical model that describes the vertical evolution of the cloud up to its effective height as a function of time, explosive quantity, atmospheric stability and horizontal wind speed, is presented. The database for this model is taken from five sets of experiments done in Israel during 2006-2009 under the "Green Field" (GF) project, using 0.25-100 kg of TNT.

    If a radiologist from 1950 could travel in time to 2011, he or she would be baffled to see how few of the radiological examinations he was familiar with, remain. We review the radiological examinations that have disappeared since X-rays were discovered, and include the causes of their disappearance. Barium studies have mainly been replaced by endoscopy, oral cholecystography by ultrasound, and intravenous urography by CT-scan. Angiography by means of a direct puncture of carotid artery and aorta has been replaced by Seldinger angiography. Pneumencephalography and myelography have been replaced by CT and MRI. Bronchography has been replaced by bronchoscopy and CT-scan, arthrography by MRI and arthroscopy. Many other radiological examinations have been replaced by ultrasound, CT or MRI. PMID:21447222

    One of the challenges of today's healthcare is that data from radiology is heterogeneous, stored and managed in silos created by PACS vendors. Also seen is a lack of coordinated use of harmonized reference information models and established healthcare standards. Radiology in Region Västra Götaland has been entering the world of "Big Data" since 2006, 34 departments split into 4 private image center, 2 small-size hospital, 4 middle-sized hospital groups and one University hospital. Using the same information infrastructure as a means of collaborating and sharing information between. As an organization building for the future we must meet the values and requirements of the stakeholders and count the patient as the major actor. Can "Big Data" analytics be a valuable asset from a regional management perspective? Our initial findings indicates that this is the case, based on three different perspectives - work practice changes, understanding data quality when sharing information and introducing new services in work practice. Going from local to enterprise workflow utilizing the power of "Big Data", not only by volume but also by combining diverse sources and aggregate the information domains, visualize new trends as well as dependencies more effectively. Building trust by the use of Big Data in healthcare involves a long and winding journey, but the persevering infrastructure-oriented organization will give new ways of collaboration for the enterprise it serves. It also involves continuous negotiation with people concerning how and why they should collaborate with new actors within the region to achieve patient centric care. This will nurture a more open-minded, hopeful and life-affirming holistic approach involving all stakeholders, newcomers' specialists and patients.

    Diversity can take many forms. One type of recent focus is generational differences and intergenerational issues. Much research exists regarding generational differences in the workplace and in healthcare as a whole. Very little has been done on generational differences within the field of radiology. An analysis of current research of generational differences within radiology, nursing, and healthcart in general was performed to identify current trends and establish similarities and discordance in available studies.

    2015-01-01

    At Houston Methodist Hospital, Commit to Sit is a program that encourages radiology professionals to communicate with patients in a way that demonstrates compassion, respect, empathy, and competence in order to foster a trusting relationship. Using active and empathic listening, dialogue is received and understood in the way it was intended, creating a patient centric environment resulting in high quality, safe patient care with improved outcomes. The implicit understanding derived from results and outcomes confirms the fact that patients prefer the radiology staff to sit while communicating with them. This understanding allows the voice of the patient to be heard and should be a consistent practice among all staff. PMID:26485897

    Radiology is a key specialty within a liver transplant program. Interventional techniques not only contribute to graft and recipient survival but also allow appropriate patient selection and ensure that recipients with severe liver decompensation, hepatocellular carcinoma or portal hypertension are transplanted with the best chance of prolonged survival. Equally inappropriate selection for these techniques may adversely affect survival. Liver transplantation is a dynamic field of innovative surgical techniques with a requirement for interventional radiology to parallel these developments. This paper reviews the current practice within a major European center for adult and pediatric transplantation.

    As health care moves to value orientation, radiology's traditional business model faces challenges to adapt. The authors describe a strategic value framework that radiology practices can use to best position themselves in their environments. This simplified construct encourages practices to define their dominant value propositions. There are 3 main value propositions that form a conceptual triangle, whose vertices represent the low-cost provider, the product leader, and the customer intimacy models. Each vertex has been a valid market position, but each demands specific capabilities and trade-offs. The underlying concepts help practices select value propositions they can successfully deliver in their competitive environments. PMID:23245438

  2. Setting up a regulatory compliance standard in today`s economy

    1994-12-31

    The economy, particularly in California, has forced the regulated community to begin streamlining and re-organization. The focus of industry today is survival. This translates into a lean staff with the dilemma of implementing and maintaining regulatory compliance on a low budget. In some instances financial resources have been absolved. Such circumstances allow innovation to excel to its highest peak. Setting up a compliance standard for an organization will allow the organization to effectively manage regulatory programs. Such a standard will define the regulatory obligations of the organization, particularly recognizing when you have exceeded the requirements. Compliance standards are intended to breed consistency among staff, while confirming that regulatory requirements have been met (particularly valuable in the mist of an external inspection).

    Radiology is a field with a high demand on information. Nowadays, a huge variety of electronic media and tools exists in addition to the classical media. Asynchronous and synchronous e-learning are constantly growing and support radiology with case collections, webinars and online textbooks. Various internet resources, social media and online courses have been established. Dynamic websites show a variety of interactive elements and it is easier and faster to access large amounts of data. Social media have an exponentially growing number of users and enable an efficient collaboration as well as forming professional networks. Massive open online courses (MOOCs) complete the offer of education and increase the opportunity to take part in educational activities. Apart from the existing variety of resources it is essential to focus on a critical selection for using these radiological media. It is reasonable to combine classical and electronic media instead of a one-sided use. As dynamic as the progress in the field of radiological media and its tools may be, the personal contact remains and should be maintained. PMID:24449282

    The migration of imaging reports to electronic medical record systems holds great potential in terms of advancing radiology research and practice by leveraging the large volume of data continuously being updated, integrated, and shared. However, there are significant challenges as well, largely due to the heterogeneity of how these data are formatted. Indeed, although there is movement toward structured reporting in radiology (ie, hierarchically itemized reporting with use of standardized terminology), the majority of radiology reports remain unstructured and use free-form language. To effectively "mine" these large datasets for hypothesis testing, a robust strategy for extracting the necessary information is needed. Manual extraction of information is a time-consuming and often unmanageable task. "Intelligent" search engines that instead rely on natural language processing (NLP), a computer-based approach to analyzing free-form text or speech, can be used to automate this data mining task. The overall goal of NLP is to translate natural human language into a structured format (ie, a fixed collection of elements), each with a standardized set of choices for its value, that is easily manipulated by computer programs to (among other things) order into subcategories or query for the presence or absence of a finding. The authors review the fundamentals of NLP and describe various techniques that constitute NLP in radiology, along with some key applications. PMID:26761536

  5. Radiology of liver circulation

    SciTech Connect

    Hermine, C.L.

    1985-01-01

    This book proposes that careful evaluation of the arterioportogram is the cornerstone in assessing portal flow obstruction, being the most consistent of all observations including liver histology, portal venous pressure, size and number of portosystemic collaterals, and wedged hepatic venous pressure. Very brief chapters cover normal hepatic circulation and angiographic methods. Contrast volumes and flow rates for celiac, hepatic, and superior mesenteric injection are given, with the timing for venous phase radiographs. In the main body of the text, portal obstruction is divided very simply into presinusoidal (all proximal causes) and postsinusoidal (all distal causes, including Budd-Chiari). Changes are discussed regarding the splenic artery and spleen; hepatic artery and its branches; portal flow rate and direction; and arterioportal shunting and portosystemic collateral circulation in minimal, moderate, severe, and very severe portal obstruction and in recognizable entities such as prehepatic portal and hepatic venous obstructions. The major emphasis in this section is the recognition and understanding of flow changes by which level and severity of obstruction are assessed (not simply the anatomy of portosystemic collateral venous flow). Excellent final chapters discuss the question of portal hypertension without obstruction, and the contribution of arterioportography to the treatment of portal hypertension, again with an emphasis on hemodynamics before and after shunt surgery. There is a fascinating final chapter on segmental intrahepatic obstruction without portal hypertension that explains much of the unusual contrast enhancement sometimes seen in CT scanning of hepatic mass lesions.

    This report summarizes and documents the results of the radiological surveys conducted over the surface of the 100-DR-1 Operable Unit, Hanford Site, Richland, Washington. In addition, this report explains the survey methodology using the Ultrasonic Ranging and Data System (USRADS). The 100-DR-1 radiological survey field task consisted of two activities: characterization of the operable unit-specific background conditions and the radiological survey of the operable unit surface area. The survey methodology was based on utilization of USRADS for automated recording of the gross gamma radiation levels at or near 6 in. and at 3 ft from the surface soil. The purpose of the survey is to identify the location of unidentified subsurface radioactive material areas and any surface contamination associated with these areas. The radiological surveys were conducted using both a digital count rate meter with a NaI detector reporting in counts per minute (CPM) and a dose rate meter reporting micro-Roentgen per hour (uR) connected to a CHEMRAD Tennessee Corp. Series 2000 USRADS. The count rate meter was set for gross counting, i.e., Window ``out``. The window setting allows detection of low, intermediate, and high energy photons. The USRADS equipment is used to record the detector readings verses the location of the readings, generate a map of the survey area, and save the data on computer storage media.

    ABSTRACT The mission of radiological dispersal device (RDD) nuclear forensics is to identify the provenance of nuclear and radiological materials used in RDDs and to aid law enforcement in tracking nuclear materials and routes. The application of databases to radiological forensics is to match RDD source material to a source model in the database, provide guidance regarding a possible second device, and aid the FBI by providing a short list of manufacturers and distributors, and ultimately to the last legal owner of the source. The Argonne/Idaho National Laboratory RDD attribution database is a powerful technical tool in radiological forensics. The database (1267 unique vendors) includes all sealed sources and a device registered in the U.S., is complemented by data from the IAEA Catalogue, and is supported by rigorous in-lab characterization of selected sealed sources regarding physical form, radiochemical composition, and age-dating profiles. Close working relationships with global partners in the commercial sealed sources industry provide invaluable technical information and expertise in the development of signature profiles. These profiles are critical to the down-selection of potential candidates in either pre- or post- event RDD attribution. The down-selection process includes a match between an interdicted (or detonated) source and a model in the database linked to one or more manufacturers and distributors.

    2011-01-01

    X-ray services were first established in Singapore in 1898. With the opening of the General Hospital in 1926, there was subsequent increase in workload. However, a radiology department was not formed until the 1950s. Angiography was introduced in the same decade initially for diagnosis. By the 1960s and 1970s, both vascular and non-vascular interventions were performed. Subsequently, interventional radiology experienced exponential growth, with newer technology and better facilities established over the past 3 decades. With more trained interventional radiologists, the service is currently available in all public hospitals and in most private hospitals in Singapore today. It is envisaged that structured training and formal credentialing will be established, eventually leading to recognition of interventional radiology as a specialty in its own right. PMID:22291858

    Lawrence Livermore National Laboratory (LLNL) is redesigning its Computer-Based Training (CBT) program for radiological workers. The redesign represents a major effort to produce a single, highly interactive and flexible CBT program that will meet the training needs of a wide range of radiological workers--from researchers and x-ray operators to individuals working in tritium, uranium, plutonium, and accelerator facilities. The new CBT program addresses the broad diversity of backgrounds found at a national laboratory. When a training audience is homogeneous in terms of education level and type of work performed, it is difficult to duplicate the effectiveness of a flexible, technically competent instructor who can tailor a course to the express needs and concerns of a course's participants. Unfortunately, such homogeneity is rare. At LLNL, they have a diverse workforce engaged in a wide range of radiological activities, from the fairly common to the quite exotic. As a result, the Laboratory must offer a wide variety of radiological worker courses. These include a general contamination-control course in addition to radioactive-material-handling courses for both low-level laboratory (i.e., bench-top) activities as well as high-level work in tritium, uranium, and plutonium facilities. They also offer training courses for employees who work with radiation-generating devices--x-ray, accelerator, and E-beam operators, for instance. However, even with the number and variety of courses the Laboratory offers, they are constrained by the diversity of backgrounds (i.e., knowledge and experience) of those to be trained. Moreover, time constraints often preclude in-depth coverage of site- and/or task-specific details. In response to this situation, several years ago LLNL began moving toward computer-based training for radiological workers. Today, that CBT effort includes a general radiological safety course developed by the Department of Energy's Hanford facility and a

    2014-02-01

    Recent media publications have indicated a tough job market in medical specialty positions for medical school graduates, specifically in the field of radiology. Internet search tools, such as Google Trends, have proved useful in the prediction of certain diseases on the basis of the search volume index for a specific term. The authors hypothesized that online search tools might be useful in the prediction of US medical school graduates' interest in residency positions in radiology. Google Trends indicated an increase over time in searches for "radiology salary" and a decrease over time in searches for "radiology residency." National Resident Matching Program results for diagnostic radiology showed an increase from 2004 to 2009 in the percentage of US graduates entering radiology but a dramatic drop from 2010 to 2013. This occurred even while the total number of US graduates active in the National Resident Matching Program increased. This finding might have been foretold on the basis of online query result trends. Online search data may be a useful insight into the interests of US medical school graduates and may be predictive of unfilled radiology residency positions and eventual increased shortages of community radiologists coming from US medical schools.

    The numbers of nurse practitioners and physician assistants are increasing throughout the entire health care enterprise, and a similar expansion continues within radiology. Some practices have instead embraced radiologist assistants. The increased volume of services rendered by this growing nonphysician provider subset of the health care workforce within and outside of radiology departments warrants closer review. The authors evaluate the recent literature and offer recommendations to radiology practices regarding both regulatory and scope-of-practice issues related to these professionals. Additionally, billing and compliance issues for care provided by nurse practitioners, physician assistants, and radiologist assistants are detailed. An analysis of the integration of these professionals into interventional and diagnostic radiology practices, as well as potential implications for medical education, is provided in the second part of this series.

    Abstract The unanticipated magnetic resonance imaging (MRI) detection in the brain of asymptomatic subjects of white matter lesions suggestive of multiple sclerosis has recently been named as radiologically isolated syndrome (RIS). The pathophysiological processes of RIS remain largely unknown and questions as to whether gray matter alterations actually occur in this entity are yet to be investigated in more detail. By means of a 3 T multimodal MRI approach, we searched for cortical and deep gray matter changes in a cohort of RIS patients. Seventeen RIS patients, 17 clinically isolated syndrome (CIS) patients (median disease duration from symptom onset = 12 months), and 17 healthy controls underwent MRI and neuropsychological testing. Normalized deep gray matter volumes and regional cortical thickness were assessed using FreeSurfer. SIENAX was used to obtain normalized global and cortical brain volumes. Voxelwise morphometry analysis was performed by using SPM8 software to localize regions of brain tissue showing significant changes of fractional anisotropy or mean diffusivity. Although no differences were observed between CIS and healthy controls groups, RIS patients showed significantly lower normalized cortical volume (673 ± 27.07 vs 641 ± 35.88 [cm3 × 103, Tukey P test = 0.009) and mean thalamic volume (0.0051 ± 0.4 vs 0.0046 ± 0.4 mm, P = 0.014) compared with healthy controls. RIS patients also showed significant thinning in a number of cortical areas, that were primarily distributed in frontal and temporal lobes (P < 0.05, uncorrected). Strong correlations were observed between T2-white matter lesion volume and regional cortical thickness (rho spearman ranging from 0.60 to 0.80). Our data suggest that white matter lesions on T2-weighted images are not the only hallmark of RIS. Future longitudinal studies with larger samples are warranted to better clarify the effect of RIS-related white matter lesions on gray matter

    Fellingham, Linda L.; Kohli, Jagdish C.

    1995-11-01

    The Radiologic Image Communication and Archive (RICA) service is designed to provide a shared archive for medical images to the widest possible audience of customers. Images are acquired from a number of different modalities, each available from many different vendors. Images are acquired digitally from those modalities which support direct digital output and by digitizing films for projection x-ray exams. The RICA Central Archive receives standard DICOM 3.0 messages and data streams from the medical imaging devices at customer institutions over the public telecommunication network. RICA represents a completely scalable resource. The user pays only for what he is using today with the full assurance that as the volume of image data that he wishes to send to the archive increases, the capacity will be there to accept it. To provide this seamless scalability imposes several requirements on the RICA architecture: (1) RICA must support the full array of transport services. (2) The Archive Interface must scale cost-effectively to support local networks that range from the very small (one x-ray digitizer in a medical clinic) to the very large and complex (a large hospital with several CTs, MRs, Nuclear medicine devices, ultrasound machines, CRs, and x-ray digitizers). (3) The Archive Server must scale cost-effectively to support rapidly increasing demands for service providing storage for and access to millions of patients and hundreds of millions of images. The architecture must support the incorporation of improved technology as it becomes available to maintain performance and remain cost-effective as demand rises.

    Techniques for estimation of biological age are constantly evolving and are finding daily application in the forensic radiology field in cases concerning the estimation of the chronological age of a corpse in order to reconstruct the biological profile, or of a living subject, for example in cases of immigration of people without identity papers from a civil registry. The deposition of teeth secondary dentine and consequent decrease of pulp chamber in size are well known as aging phenomena, and they have been applied to the forensic context by the development of age estimation procedures, such as Kvaal-Solheim and Cameriere methods. The present study takes into consideration canines pulp chamber volume related to the entire teeth volume, with the aim of proposing new regression formulae for age estimation using 91 cone beam computerized scans and a freeware open-source software, in order to permit affordable reproducibility of volumes calculation.

    The application of ionizing radiation in medicine seems to be a safe procedure for patients as well as for occupational exposition to personnel. The developments in interventional radiology with fluoroscopy and dose-intensive interventions require intensified radiation protection. It is recommended that all available tools should be used for this purpose. Besides the options for instruments, x‑ray protection at the intervention table must be intensively practiced with lead aprons and mounted lead glass. A special focus on eye protection to prevent cataracts is also recommended. The development of cataracts might no longer be deterministic, as confirmed by new data; therefore, the International Commission on Radiological Protection (ICRP) has lowered the threshold dose value for eyes from 150 mSv/year to 20 mSv/year. Measurements show that the new values can be achieved by applying all X‑ray protection measures plus lead-containing eyeglasses. PMID:26913507

    2005-03-01

    A basic knowledge of financial accounting can help radiologists analyze business opportunities and examine the potential impacts of new technology or predict the adverse consequences of new competitors entering their service area. The income statement, balance sheet, and cash flow statement are the three basic financial statements that document the current financial position of the radiology practice and allow managers to monitor the ongoing financial operations of the enterprise. Pro forma, or hypothetical, financial statements can be generated to predict the financial impact of specific business decisions or investments on the profitability of the practice. Sensitivity analysis, or what-if scenarios, can be performed to determine the potential impact of changing key revenue, investment, operating cost or financial assumptions. By viewing radiology as both a profession and a business, radiologists can optimize their use of scarce economic resources and maximize the return on their financial investments. PMID:17411807

    Interventional radiological percutaneous procedures are becoming all the more important in the curative or palliative management of elderly frail patients with multiple underlying comorbidities. They may serve either as alternative primary minimally invasive therapies or adjuncts to traditional surgical treatments. The present report provides a concise review of the most important interventional radiological procedures with a special focus on the treatment of the primary debilitating pathologies of the elderly population. The authors elaborate on the scientific evidence and latest developments of thermoablation of solid organ malignancies, palliative stent placement for gastrointestinal tract cancer, airway stenting for tracheobronchial strictures, endovascular management of aortic and peripheral arterial vascular disease, and cement stabilization of osteoporotic vertebral fractures. The added benefits of high technical and clinical success coupled with lower procedural mortality and morbidity are highlighted. PMID:19503761

  18. Understanding Mechanisms of Radiological Contamination

    Rick Demmer; John Drake; Ryan James, PhD

    2014-03-01

    Over the last 50 years, the study of radiological contamination and decontamination has expanded significantly. This paper addresses the mechanisms of radiological contamination that have been reported and then discusses which methods have recently been used during performance testing of several different decontamination technologies. About twenty years ago the Idaho Nuclear Technology Engineering Center (INTEC) at the INL began a search for decontamination processes which could minimize secondary waste. In order to test the effectiveness of these decontamination technologies, a new simulated contamination, termed SIMCON, was developed. SIMCON was designed to replicate the types of contamination found on stainless steel, spent fuel processing equipment. Ten years later, the INL began research into methods for simulating urban contamination resulting from a radiological dispersal device (RDD). This work was sponsored by the Defense Advanced Research Projects Agency (DARPA) and included the initial development an aqueous application of contaminant to substrate. Since 2007, research sponsored by the US Environmental Protection Agency (EPA) has advanced that effort and led to the development of a contamination method that simulates particulate fallout from an Improvised Nuclear Device (IND). The IND method diverges from previous efforts to create tenacious contamination by simulating a reproducible “loose” contamination. Examining these different types of contamination (and subsequent decontamination processes), which have included several different radionuclides and substrates, sheds light on contamination processes that occur throughout the nuclear industry and in the urban environment.

  19. Telemetry of Aerial Radiological Measurements

    2002-10-01

    Telemetry has been added to National Nuclear Security Administration's (NNSA's) Aerial Measuring System (AMS) Incident Response aircraft to accelerate availability of aerial radiological mapping data. Rapid aerial radiological mapping is promptly performed by AMS Incident Response aircraft in the event of a major radiological dispersal. The AMS airplane flies the entire potentially affected area, plus a generous margin, to provide a quick look at the extent and severity of the event. The primary result of the AMS Incident Response over flight is a map of estimated exposure rate on the ground along the flight path. Formerly, it was necessary to wait for the airplane to land before the map could be seen. Now, while the flight is still in progress, data are relayed via satellite directly from the aircraft to an operations center, where they are displayed and disseminated. This permits more timely utilization of results by decision makers and redirection of the mission to optimize its value. The current telemetry capability can cover all of North America. Extension to a global capability is under consideration.

  20. Radiology uses of the Internet.

    1995-01-01

    The Internet promises to be an essential resource for radiology administrators. In addition to offering remarkable access to colleagues all over the world, the Internet offers specialized information resources for radiology, many of which are described in this article. The Internet is many networks that communicate with each other and whose general purpose is to share information. Although there are several consortium organizations that support and regulate it, no single body or organization "owns" the Internet. Many employees and students at large teaching centers already have access to the Internet through their institution's connection. Individuals and small institutions can contract with independent service providers for Internet access. Internet functions covered in this article include: e-mail, listservs, newsgroups, file transfer protocols, Gopher, and the World Wide Web. The rapid pace of information exchange is making the world of radiology smaller and more intimate. Communication and knowledge are becoming so accessible that individuals are privy to the most minute happenings in the industry. Sharing information on the Internet will benefit not only individual users and the industry, but also patients. PMID:10161227

    Rather than perpetuating the struggle, "who controls the PACS, Radiology or Information Technology (IT)," Community Hospital of the Monterey Peninsula (CHOMP) took the approach of incorporating IT support within the Radiology Department. CHOMP faced the challenge of staffing Radiology computer systems and networks by using a two-pronged approach; promoting and training clinical staff in IT functions and transferring an experienced IT person into the Radiology Department. Roles and responsibilities are divided. CHOMP's IT Department supports the Radiology Department's desktop devices, PCs, printers, and standard peripherals; while the department's DICOM print and archive network, specialized hardware (e.g., Merge DICOM interface computers), and applications are supported by the Radiology Department. The IT Department provides operating system support for multi-user VMS, Unix, and NT-based systems, e.g. Sun Solaris for the DICOM archive, and Windows NT for Mitra PACS Broker, the HL7/DICOM interface engine. IT also supports network communications, i.e., network electronics (routers, switches, etc.), TCP/IP communications, and network traffic analysis; and OS operations support for major Radiology systems, e.g. back-ups and off-site tape storage. Radiology staff provides applications support and troubleshooting, including analyst functions for RIS; and are the first point of contact with the Radiology systems vendors, e.g., GE Medical, or Siemens. The Radiology Department's senior IT person, the Clinical Technology Coordinator, transferred from CHOMP's IT Department after 7 years in that department. She performs analysis and design associated with Radiology's computer systems, coordinates development of the department's strategic plan, evaluates vendor proposals, and assists the department with product and application selection. Her IT experience and growing knowledge of Radiology's clinical tasks enhances communications between the Radiology and IT departments. Formal

  4. Design of a large network for radiological image data.

    Ruffolo, Marisa; Daskin, Mark S; Sahakian, Alan V; Berry, Randall A

    2007-01-01

    Radiological imaging is a rapidly growing business. The field is quickly evolving from films to electronic or digital imaging. By the year 2015, the amount of radiological image data that will have been generated in the U.S. alone is projected to be between 100 and 300 000 PB. (1 PB equals 2(50) B or about 10(15) B.) As the volume of radiological data increases, the need to transmit the data over long distances also increases. For example, radiologists in Chicago, India, or Israel, working in the same medical practice, may read images taken in Chicago. Globally distributed research requires that images be transmitted around the world. Radiologists and researchers want to be able to download files containing hundreds of megabytes in seconds. This service requirement suggests that multiple copies of images should be retained in globally distributed databases to minimize access and transmission delays. Key design issues for such a database include the location of the data repositories relative to the generating and retrieval (reading) sites and the number and location of the copies of the files that are generated. In this paper, we approximate the time to retrieve images stored in city j by a radiologist in city k at time period t. Next, we formulate a model designed to minimize the average retrieval time weighted over all demands. We briefly outline a nested Lagrangian relaxation approach to the problem. Computational results are then summarized. The paper ends with conclusion and directions for future research. PMID:17249401

    The Society for Computer Applications in Radiology (SCAR) Transforming the Radiological Interpretation Process (TRIP) Initiative aims to spearhead research, education, and discovery of innovative solutions to address the problem of information and image data overload. The initiative will foster inter-disciplinary research on technological, environmental and human factors to better manage and exploit the massive amounts of data. TRIP will focus on the following basic objectives: improving the efficiency of interpretation of large data sets, improving the timeliness and effectiveness of communication, and decreasing medical errors. The ultimate goal of the initiative is to improve the quality and safety of patient care. Interdisciplinary research into several broad areas will be necessary to make progress in managing the ever-increasing volume of data. The six concepts involved include: human perception, image processing and computer-aided detection (CAD), visualization, navigation and usability, databases and integration, and evaluation and validation of methods and performance. The result of this transformation will affect several key processes in radiology, including image interpretation; communication of imaging results; workflow and efficiency within the health care enterprise; diagnostic accuracy and a reduction in medical errors; and, ultimately, the overall quality of care.

  6. Methods of determining the effective dose in dental radiology.

    PubMed

    Thilander-Klang, Anne; Helmrot, Ebba

    2010-01-01

    A wide variety of X-ray equipment is used today in dental radiology, including intra-oral, orthopantomographic, cephalometric, cone-beam computed tomography (CBCT) and computed tomography (CT). This raises the question of how the radiation risks resulting from different kinds of examinations should be compared. The risk to the patient is usually expressed in terms of effective dose. However, it is difficult to determine its reliability, and it is difficult to make comparisons, especially when different modalities are used. The classification of the new CBCT units is also problematic as they are sometimes classified as CT units. This will lead to problems in choosing the best dosimetric method, especially when the examination geometry resembles more on an ordinary orthopantomographic examination, as the axis of rotation is not at the centre of the patient, and small radiation field sizes are used. The purpose of this study was to present different methods for the estimation of the effective dose from the equipment currently used in dental radiology, and to discuss their limitations. The methods are compared based on commonly used measurable and computable dose quantities, and their reliability in the estimation of the effective dose. PMID:20211918

    1998-02-01

    The Safe Sites of Colorado Radiological Safety program has implemented a Safety Coach position, responsible for mentoring workers and line management by providing effective on-the-job radiological skills training and explanation of the rational for radiological safety requirements. This position is significantly different from a traditional classroom instructor or a facility health physicist, and provides workers with a level of radiological safety guidance not routinely provided by typical training programs. Implementation of this position presents a challenge in providing effective instruction, requiring rapport with the radiological worker not typically developed in the routine radiological training environment. The value of this unique training is discussed in perspective with cost-savings through better radiological control. Measures of success were developed to quantify program performance and providing a realistic picture of the benefits of providing one-on-one or small group training. This paper provides a description of the unique features of the program, measures of success for the program, a formula for implementing this program at other facilities, and a strong argument for the success (or failure) of the program in a time of increased radiological safety emphasis and reduced radiological safety budgets.

    Intestinal ischemia, which refers to insufficient blood flow to the bowel, is a potentially catastrophic entity that may require emergent intervention or surgery in the acute setting. Although the clinical signs and symptoms of intestinal ischemia are nonspecific, computed tomography (CT) findings can be highly suggestive in the correct clinical setting. In our article, we review the CT diagnosis of arterial, venous, and nonocclusive intestinal ischemia. We discuss the vascular anatomy, pathophysiology of intestinal ischemia, CT techniques for optimal imaging, key and ancillary radiological findings, and differential diagnosis. PMID:26526436

    Childhood arthritis has now been reclassified into a single internationally recognized entity of juvenile idiopathic arthritis (JIA). Radiology provides an important role in the management of JIA, in helping in the differential diagnosis, monitoring disease progression and detecting complications. Traditionally, plain radiographs have been the imaging investigation of choice but magnetic resonance imaging (MRI) and ultrasound are now providing a more effective and safer alternative. The appropriate use of sequences in MR imaging is important in the early detection of joint abnormalities in JIA. PMID:11798203

    Hip and groin pain are a common complaint among athletes of all ages, and may result from an acute injury or from chronic, repetitive trauma. Hip injuries can be intraarticular, extraarticular, or both. Labral abnormalities may occur in asymptomatic patients as well as in those with incapacitating symptoms and signs. Athletic hip injury leading to disabling intraarticular hip pain most commonly involves labral tear. The extraarticular causes are usually the result of overuse activity, leading to inflammation, tendonitis, or bursitis. In clinical practice, the term athletic pubalgia is used to describe exertional pubic or groin pain. PMID:21419955

    Purpose. To describe the current state and limitations to interventional radiology (IR) in Canada through a large, national survey of Canadian interventional radiologists. Methods. An anonymous online survey was offered to members of the Canadian Interventional Radiology Association (CIRA). Only staff radiologists were invited to participate. Results. Seventy-five (75) responses were received from a total of 247, giving a response rate of 30%. Respondents were split approximately equally between academic centers (47%) and community practice (53%), and the majority of interventional radiologists worked in hospitals with either 200-500 (49%) or 500-1,000 (39%) beds. Procedures listed by respondents as most commonly performed in their practice included PICC line insertion (83%), angiography and stenting (65%), and percutaneous biopsy (37%). Procedures listed as not currently performed but which interventional radiologists believed would benefit their patient population included radiofrequency ablation (36%), carotid stenting (34%), and aortic stenting (21%); the majority of respondents noted that a lack of support from referring services was the main reason for not performing these procedures (56%). Impediments to increasing scope and volume of practice in Canadian IR were most commonly related to room or equipment shortage (35%), radiologist shortage (33%), and a lack of funding or administrative support (28%). Conclusion. Interventional radiology in Canada is limited by a number of factors including funding, manpower, and referral support. A concerted effort should be undertaken by individual interventional radiologists and IR organizations to increase training capacity, funding, remuneration, and public exposure to IR in order to help advance the subspecialty.

  3. Co-responsibility: a new horizon for today's health care?

    PubMed

    Devisch, Ignaas

    2012-06-01

    In this article, we focus at a key concept of today's healthcare, namely responsibility. Personal responsibility is so important today because it is obvious that the way society is organized, many people are facing a lot of difficulties to live their lives in a responsible way. We explicitly obtain an analysis of responsibility from a view which avoids the binary thinking which is so remarkably present in today's health care discourse. The aim of this pilot study is therefore to open up the horizon of the use of responsibility in today's healthcare. We develop the notion of 'co-responsibility' to understand how individuals, despite the fact they are responsible for their own agency, are always also affected by an ought which contaminates their efforts to fulfill their duties and obligations. We discuss co-responsibility not as conclusion or a magic formula to all problems, but as a new starting point of which we have to explore the opportunities for current and future health care dilemmas.

  13. Pediatric Interventional Radiology: Vascular Interventions.

    PubMed

    Kandasamy, Devasenathipathy; Gamanagatti, Shivanand; Gupta, Arun Kumar

    2016-07-01

    Pediatric interventional radiology (PIR) comprises a range of minimally invasive diagnostic and therapeutic procedures that are performed using image guidance. PIR has emerged as an essential adjunct to various surgical and medical conditions. Over the years, technology has undergone dramatic and continuous evolution, making this speciality grow. In this review, the authors will discuss various vascular interventional procedures undertaken in pediatric patients. It is challenging for the interventional radiologist to accomplish a successful interventional procedure. There are many vascular interventional radiology procedures which are being performed and have changed the way the diseases are managed. Some of the procedures are life saving and have become the treatment of choice in those patients. The future is indeed bright for the practice and practitioners of pediatric vascular and non-vascular interventions. As more and more of the procedures that are currently being performed in adults get gradually adapted for use in the pediatric population, it may be possible to perform safe and successful interventions in many of the pediatric vascular lesions that are otherwise being referred for surgery.

  14. Local area networks for radiology.

    PubMed

    Dwyer, S J; Mankovich, N J; Cox, G G; Bauman, R A

    1988-11-01

    This article is a tutorial on local area networks (LAN) for radiology applications. LANs are being implemented in radiology departments for the management of text and images, replacing the inflexible point-to-point wiring between two devices (computer-to-terminal). These networks enable the sharing of computers and computer devices, reduce equipment costs, and provide improved reliability. Any LAN must include items from the following four categories: transmission medium, topology, data transmission mode, and access protocol. Media for local area networks are twisted pair, coaxial, and optical fiber cables. The topology of these networks include the star, ring, bus, tree, and circuit-switching. Data transmission modes are either analog signals or digital signals. Access protocol methods include the broadcast bus system and the ring system. A performance measurement for a LAN is the throughput rate as a function of the number of active computer nodes. Standards for LANs help to ensure that products purchased from multiple manufacturers will operate successfully. PMID:3154655

    The aim of this study is to evaluate dose values in patients and staff involved in some interventional radiology procedures. Doses have been measured using thermoluminescent dosemeters for single procedures (such as renal and cerebral arteriography, transjungular intrahepatic portasystemic shunt (TIPS) and chemoembolization). The magnitude of doses through the hands of interventional radiologists has been studied. Dose levels were evaluated in three points for patients (eye, thyroid and gonads). The dose-area product (DAP) was also investigated using a Diamentor (PTW-M2). The dose in extremities was estimated for a professional who generally performed one TIPS, two chemoembolizations, two cerebral arteriographies and two renal arteriographies in a week. The estimated annual radiation dose was converted to effective dose as suggested by the 453-MS/Brazil norm The annual dose values were 137.25 mSv for doctors, 40.27 mSv for nurses and 51.95 mSv for auxiliary doctors, and all these annual dose values are below the limit established. The maximum values of the dose obtained for patients were 6.91, 10.92 and 15.34 mGy close to eye, thyroid and gonads, respectively. The DAP values were evaluated for patients in the same interventional radiology procedures. The dose and DAP values obtained are in agreement with values encountered in the literature.

  16. Facing Today's Exploration Challenges in the Gulf of Mexico

    NASA Astrophysics Data System (ADS)

    Detomo, R.

    2005-05-01

    The Gulf of Mexico represents one of the most intensively explored basins in the world, and yet it still delivers significant new material oil and gas discoveries every year. Because of it high productivity, geologic complexity, competitive acreage access and large profitability margins, the Gulf of Mexico presents many industry-leading challenges to Exploration today. For major companies exploring for oil and gas in the Gulf of Mexico today, their challenge is to "safely, responsibly and profitably find and produce reduced accumulations in increasingly hostile settings." The GoM serves as the sportsman's playground for a significant population located in and around its waters, and therefore, operating safely and responsibly are unassailable moral and operational standards by which we sustain future development, and maintain our license to operate. With that as a backdrop, today's challenges are driven by the nature of where the business is looking for new reserves in this extremely mature basin. These "Opportunities" encompass the following: 1) large, under-explored, sub-salt areas, characterized by poor seismic imaging, uncertain geologic regimes and potentially dangerous overpressures, 2) deep true-vertical-depth opportunities in older rocks that challenge our understanding of reservoir quality prediction and hydrocarbon systems, and are at the edge of today's drilling technologies, 3) access to sensitive areas including the eastern GoM-Florida shelf, coastal areas and international borders, 4) challenging "small accumulation" discoveries that cannot support expensive appraisal or development options, are remote to infrastructure or inefficiently produce the reservoir, and finally 5) new play development, which is challenged by long maturation cycles, small acreage blocks, intense international competition, and rapid lease rolls. This talk will consider what Shell and the Oil & Gas Industry does today to succeed in this arena, and specifically will show examples

  18. Accelerators in our past, present, and future: A challenge to radiological protection in the twenty-first century

    SciTech Connect

    Thomas, R.H. |

    1993-09-01

    The foundations of many of the subdisciplines of radiological protection laid in accelerator laboratories began with the invention of accelerators. This paper suggests that the discipline of accelerator radiological protection has played and will continue play a more significant part in our lives than is generally recognized. A brief review of some existing uses of accelerators by society is given, and a few probable future uses are described. These future applications will result in the exposure of accelerator (or {open_quotes}mixed{close_quotes}) radiation fields to an increased population. Consequently, what are perceived to be the rather specialized concerns of today`s accelerator health physicists will -- by necessity -- become of general interest to all health physicists.

    Summary Background The role of radiology is of utmost importance not only in diagnosing s-OHSS but also in ruling out other cystic ovarian diseases and to determine the underlying etiology and course of the disease. We presented a radiological algorithm for diagnosing the various causes of s-OHSS. Case Report A 26-year-old female, gravida one was referred to radiology department with history of lower abdominal pain, nausea and vomiting since 2 days which was gradual in onset and progression. The patient had no significant medical and surgical history. Conclusions This article illustrates and emphasizes that diagnosis of s-OHSS and its etiology can be completely evaluated radiologically. Biochemical markers will confirm the radiological diagnosis. PMID:25960820

    PubMed

    Powers, Kevin J

    2005-01-01

    A total of 326 programs are represented in the data collected. Based on the average number of full- and part-time faculty members reported per program, this survey represents more than 1500 faculty positions. Based on the forecast of retirement and career change for all faculty members, there will be a turnover of 700 to 800 positions over the next 5 to 10 years. Part-time/adjunct faculty vacancies are expected to create the greatest number of opportunities for technologists to make the transition to education, with approximately one third of current part-time/adjunct educators planning on leaving radiologic sciences education within 5 years. To encourage retention of part-time/adjunct educators, annual evaluations should be modified to recognize the important educational role these instructors play. There is a need to create enthusiasm and interest in education as a career pathway for radiologic technologists. Resources are needed that help radiologic technologists make the transition to teaching. Finally, the retention of educators must be emphasized. Program applicant trends indicate radiologic technology students are older, have prior postsecondary education experience or are making a career change. This data emphasizes the need for educators, both full time and part time, to understand the characteristics and needs of the adult learner. Adult learners bring a wealth of education, experience and life skills that create both opportunities and challenges in the classroom and clinical setting. All categories of respondents indicated that their current salaries were greater than those of program graduates in their firstjob. Of interest is that 1 in 5 (20%) of part-time/adjunct educators indicated the opposite--that program graduates earn more in their firstjob than educators earn. When asked about salaries if working full time in clinical practice, the majority of all groups indicated their salary would be about the same or would decrease. Only 20% of program

    PubMed

    Henry, Linda L

    2005-01-01

    Childhood obesity is at epidemic proportions in the United States today. This epidemic has created a public health crisis. Although several initiatives are under way to address childhood obesity, including legislative bills before Congress and a call by the National Academy of Sciences for society to band together to stop the rise in the rates of childhood obesity, none of these efforts address what can be done today to help those youth that are considered morbidly obese and who have failed to find solutions with the standard medical treatment plan. This article discusses the use of bariatric surgery as a possible solution, presents a case study to illustrate the impact bariatric surgery can have on youth who are morbidly obese, and defines the pediatric nurse's role in helping to assure that youth are included in the current legislative process.

    Transparent Volume Imaging began with the stereo xray in 1895 and ended for most investigators when radiation safety concerns eliminated the second view. Today, similiar images can be generated by the computer without safety hazards providing improved perception and new means of image quantification. A volumetric workstation is under development based on an operational prototype. The workstation consists of multiple symbolic and numeric processors, binocular stereo color display generator with large image memory and liquid crystal shutter, voice input and output, a 3D pointer that uses projection lenses so that structures in 3 space can be touched directly, 3D hard copy using vectograph and lenticular printing, and presentation facilities using stereo 35mm slide and stereo video tape projection. Volumetric software includes a volume window manager, Mayo Clinic's Analyze program and our Digital Stereo Microscope (DSM) algorithms. The DSM uses stereo xray-like projections, rapidly oscillating motion and focal depth cues such that detail can be studied in the spatial context of the entire set of data. Focal depth cues are generated with a lens and apeture algorithm that generates a plane of sharp focus, and multiple stereo pairs each with a different plane of sharp focus are generated and stored in the large memory for interactive selection using a physical or symbolic depth selector. More recent work is studying non-linear focussing. Psychophysical studies are underway to understand how people perce ive images on a volumetric display and how accurately 3 dimensional structures can be quantitated from these displays.

    Few information systems today offer a clear and flexible means to define and manage the automated part of radiology processes. None of them provide a coherent and scalable architecture that can easily cope with heterogeneity and inevitable local adaptation of applications. Most importantly, they often lack a model that can integrate clinical and administrative information to aid better decisions in managing resources, optimizing operations, and improving productivity. Digital radiology enterprises require cost-effective solutions to deliver information to the right person in the right place and at the right time. We propose a new architecture of image information management systems for digital radiology enterprises. Such a system is based on the emerging technologies in workflow management, distributed object computing, and Java and Web techniques, as well as Philips' domain knowledge in radiology operations. Our design adapts the approach of '4+1' architectural view. In this new architecture, PACS and RIS will become one while the user interaction can be automated by customized workflow process. Clinical service applications are implemented as active components. They can be reasonably substituted by applications of local adaptations and can be multiplied for fault tolerance and load balancing. Furthermore, it will provide powerful query and statistical functions for managing resources and improving productivity in real time. This work will lead to a new direction of image information management in the next millennium. We will illustrate the innovative design with implemented examples of a working prototype.

    Physician performance and outcomes are being scrutinised by health care providers to improve patient safety and cost efficiency. Patients are best served by physicians who have undergone appropriate specialist training and assessment and perform large numbers of cases to maintain their skills. The Cardiovascular and Interventional Radiological Society of Europe has put into place a curriculum for training in interventional radiology (IR) and a syllabus with an examination, the European Board of Interventional Radiology, providing evidence of attainment of an appropriate and satisfactory skill set for the safe practice of IR. This curriculum is appropriate for IR where there is a high volume of image-guided procedures in vascular and nonvascular organ systems with cross-use of minimally invasive techniques in patients with a variety of disease processes. Other specialties may require different, longer, and more focused training if their experience is “diluted” by the need to master a different skill set.

  11. Relative radiological risks derived from different TENORM wastes in Malaysia.

    2011-11-01

    In Malaysia technologically enhanced naturally occurring radioactive materials (TENORM) wastes are mainly the product of the oil and gas industry and mineral processing. Among these TENORM wastes are tin tailing, tin slag, gypsum and oil sludge. Mineral processing and oil and gas industries produce large volume of TENORM wastes that has become a radiological concern to the authorities. A study was carried out to assess the radiological risk related to workers working at these disposal sites and landfills as well as to the members of the public should these areas be developed for future land use. Radiological risk was assessed based on the magnitude of radiation hazard, effective dose rates and excess cancer risks. Effective dose rates and excess cancer risks were estimated using RESRAD 6.4 computer code. All data on the activity concentrations of NORM in wastes and sludges used in this study were obtained from the Atomic Energy Licensing Board, Malaysia, and they were collected over a period of between 5 and 10 y. Results obtained showed that there was a wide range in the total activity concentrations (TAC) of nuclides in the TENORM wastes. With the exception of tin slag and tin tailing-based TENORM wastes, all other TENORM wastes have TAC values comparable to that of Malaysia's soil. Occupational Effective Dose Rates estimated in all landfill areas were lower than the 20 mSv y(-1) permissible dose limit. The average Excess Cancer Risk Coefficient was estimated to be 2.77×10(-3) risk per mSv. The effective dose rates for residents living on gypsum and oil sludge-based TENORM wastes landfills were estimated to be lower than the permissible dose limit for members of the public, and was also comparable to that of the average Malaysia's ordinary soils. The average excess cancer risk coefficient was estimated to be 3.19×10(-3) risk per mSv. Results obtained suggest that gypsum and oil sludge-based TENORM wastes should be exempted from any radiological regulatory

  12. Quantum volume

    2015-08-01

    Quantum systems in a mechanical embedding, the breathing mode of a small particles, optomechanical system, etc. are far not the full list of examples in which the volume exhibits quantum behavior. Traditional consideration suggests strain in small systems as a result of a collective movement of particles, rather than the dynamics of the volume as an independent variable. The aim of this work is to show that some problem here might be essentially simplified by introducing periodic boundary conditions. At this case, the volume is considered as the independent dynamical variable driven by the internal pressure. For this purpose, the concept of quantum volume based on Schrödinger’s equation in 𝕋3 manifold is proposed. It is used to explore several 1D model systems: An ensemble of free particles under external pressure, quantum manometer and a quantum breathing mode. In particular, the influence of the pressure of free particle on quantum oscillator is determined. It is shown also that correction to the spectrum of the breathing mode due to internal degrees of freedom is determined by the off-diagonal matrix elements of the quantum stress. The new treatment not using the “force” theorem is proposed for the quantum stress tensor. In the general case of flexible quantum 3D dynamics, quantum deformations of different type might be introduced similarly to monopole mode.

    Over the past year, the Department of Energy (DOE) Office of Health (EH-40) has taken a leading role in the development of new standardized radiological control training programs for use throughout the DOE complex. The Department promulgated its Radiological Control (RadCon) Manual in June 1992. To ensure consistent application of the criteria presented in the RadCon Manual, standardized radiological control core training courses and training materials have been developed for implementation at all DOE facilities. In producing local training programs, standardized core courses are to be supplemented with site-specific lesson plans, viewgraphs, student handbooks, qualification standards, question banks, and wallet-sized training certificates. Training programs for General Employee Radiological Training, Radiological Worker I and II Training, and Radiological Control Technician Training have been disseminated. Also, training committees under the direction of the Office of Health (EH-40) have been established for the development of additional core training courses, development of examination banks, and the update of the existing core training courses. This paper discusses the current activities and future direction of the DOE radiological control core training program.

    Optical imaging spectroscopy is investigated as a method to estimate radiological background by spectral identification of soils, sediments, rocks, minerals and building materials derived from natural materials and assigning tabulated radiological emission values to these materials. Radiological airborne surveys are undertaken by local, state and federal agencies to identify the presence of radiological materials out of regulatory compliance. Detection performance in such surveys is determined by (among other factors) the uncertainty in the radiation background; increased knowledge of the expected radiation background will improve the ability to detect low-activity radiological materials. Radiological background due to naturally occurring radiological materials (NORM) can be estimated by reference to previous survey results, use of global 40K, 238U, and 232Th (KUT) values, reference to existing USGS radiation background maps, or by a moving average of the data as it is acquired. Each of these methods has its drawbacks: previous survey results may not include recent changes, the global average provides only a zero-order estimate, the USGS background radiation map resolutions are coarse and are accurate only to 1 km – 25 km sampling intervals depending on locale, and a moving average may essentially low pass filter the data to obscure small changes in radiation counts. Imaging spectroscopy from airborne or spaceborne platforms can offer higher resolution identification of materials and background, as well as provide imaging context information. AVIRIS hyperspectral image data is analyzed using commercial exploitation software to determine the usefulness of imaging spectroscopy to identify qualitative radiological background emissions when compared to airborne radiological survey data.

    Radiological and nuclear disasters are infrequent, but when they occur, they result in large and demonstrable health burdens. Several scenarios can result in the public's exposure to radiation. For example, radiation sources used in health care or other industries can be lost or misused. Incidents in the nuclear power industry, such as those at Chernobyl and Three Mile Island, require significant public health response. In addition, radiological terrorism can involve the use of a radiological dispersal device (RDD) or an improvised nuclear device (IND). State and local health agencies are expected to perform essential public health functions in response to any of these emergencies. PMID:20847721

    Hospital planning for chemical or radiological events is essential but all too often treated as a low priority. Although some other types of disasters like hurricanes and tornadoes may be more frequent, chemical and radiological emergencies have the potential for major disruptions to clinical care. Thorough planning can mitigate the impact of a chemical or radiological event. Planning needs to include all 4 phases of an event: mitigation (preplanning), preparation, response, and recovery. Mitigation activities should include the performance of a hazards vulnerability analysis and identification of local subject-matter experts and team leaders. PMID:25455661

    Diagnostic radiology is an integral part of percutaneous laser disc decompression (PLDD). All physicians involved in PLDD patient selection and treatment must be familiar with the imaging techniques unique to this procedure to ensure a successful outcome. The following review is based on the cumulative experience gained in performing over 150 PLDD procedures. It discusses the function of diagnostic radiology in all facets of PLDD including patient selection, intraoperative imaging, postoperative evaluation, and analysis of complications. Fundamental radiologic concepts that apply to PLDD are explained and protocols suggested to optimize results and avoid complications. PMID:10146513

    This book differs from several other presently available texts on interventional radiology in that it is explicitly not derived from the principles of catheter angiography. Abdominal interventional radiology depends as much, if not more, on ultrasonographic and computed tomographic guidance and, while perhaps less glamorous, also on conventional fluoroscopic guidance (for procedures such as urinary and biliary manipulations). Thus, while technical aspects of catheter design and manipulation can never be minimized, they are not the sole elements of successful interventional radiology in the abdomen. Relevant anatomy and pathophysiology, along with clinical aspects of medical and surgical care and thorough patient follow-up are of equal concern.

    Chest radiographs and spirometric tests were performed on 81 patients who had silicosis from two granite quarries in 1975, 73 of whom were followed up for two to 10 (mean 7.2) years. Each patient's initial and most recent chest radiographs were assessed independently by three experienced readers, and the yearly declines in forced expiratory volume in one second and forced vital capacity were estimated from two to four (mean 3.45) serial spirometric readings. Estimates of individual dust exposure were based on extensive historical data on hygiene. All but 11 patients were no longer exposed to dust by the start of follow up, but 24 (45%) of 53 patients who had simple silicosis and 11 (55%) of 20 who had the complicated disease showed radiological evidence of disease progression. In patients who had simple silicosis and showed no radiological progression the yearly declines in forced expiratory volume in one second and forced vital capacity were modest (64 ml/year and 59 ml/year, respectively), whereas significantly greater declines in lung function were seen in those who showed radiological evidence of progression (97 ml/year and 95 ml/year, respectively). In addition to radiological progression the previous average dust concentration to which patients had been exposed also influenced declines in both forced expiratory volume in one second and forced vital capacity after allowing for the effects of age, smoking, duration of exposure, history of tuberculosis, initial state of disease, and baseline lung function. The probability of radiological progression was most strongly influenced by the average dust concentration previously exposed to. The progression of simple silicosis is thus accompanied by appreciable declines in lung function and is strongly affected by previous levels of exposure to dust. PMID:3115361

    The management of the vast amounts of medical images and information generated by today's clinical services is a growing problem. The solution to the problem will increasingly require the use of advanced technologies data storage, image display, communication, and human engineering. The progress of individual technologies has been rapid; however, system integration and user acceptance of digital image management technology have been slow . Critical evaluation of the efficacy of this use of technology is essential for the evolution of picture archiving and communication system (PACS) in radiology.

    The objective of lung volume reduction surgery (LVRS) is the safe, effective, and durable palliation of dyspnea in appropriately selected patients with moderate to severe emphysema. Appropriate patient selection and preoperative preparation are prerequisites for successful LVRS. An effective LVRS program requires participation by and communication between experts from pulmonary medicine, thoracic surgery, thoracic anesthesiology, critical care medicine, rehabilitation medicine, respiratory therapy, chest radiology, and nursing. The critical analysis of perioperative outcomes has influenced details of the conduct of the procedure and has established a bilateral, stapled approach as the standard of care for LVRS. The National Emphysema Treatment Trial (NETT) remains the world's largest multi-center, randomized trial comparing LVRS to maximal medical therapy. NETT purposely enrolled a broad spectrum of anatomic patterns of emphysema. This, along with the prospective, audited collection of extensive demographic, physiologic, radiographic, surgical and quality-of-life data, has positioned NETT as the most robust repository of evidence to guide the refinement of patient selection criteria for LVRS, to assist surgeons in providing optimal intraoperative and postoperative care, and to establish benchmarks for survival, complication rates, return to independent living, and durability of response. This article reviews the evolution of current LVRS practice with a particular emphasis on technical aspects of the operation, including the predictors and consequences of its most common complications.

    To evaluate a conventional radiology image management system, by investigating information accuracy, and information delivery. To discuss the customization of a picture archival and communication system (PACS), integrated radiology information system (RIS) and hospital information system (HIS) to a high volume emergency department (ED). Materials and Methods: Two data collection periods were completed. After the first data collection period, a change in work rules was implemented to improve the quality of data in the image headers. Data from the RIS, the ED information system, and the HIS as well as observed time motion data were collected for patients admitted to the ED. Data accuracy, patient waiting times, and radiology exam information delivery were compared. Results: The percentage of examinations scheduled in the RIS by the technologists increased from 0% (0 of 213) during the first period to 14% (44 of 317) during the second (p less than 0.001). The percentage of images missing identification numbers decreased from 36% (98 of 272) during the first data collection period to 10% (56 of 562) during the second period (p less than 0.001). Conclusions: Radiologic services in a high-volume ED, requiring rapid service, present important challenges to a PACS system. Strategies can be implemented to improve accuracy and completeness of the data in PACS image headers in such an environment.

  5. Stroke volume optimization: the new hemodynamic algorithm.

    PubMed

    Johnson, Alexander; Ahrens, Thomas

    2015-02-01

    Critical care practices have evolved to rely more on physical assessments for monitoring cardiac output and evaluating fluid volume status because these assessments are less invasive and more convenient to use than is a pulmonary artery catheter. Despite this trend, level of consciousness, central venous pressure, urine output, heart rate, and blood pressure remain assessments that are slow to be changed, potentially misleading, and often manifested as late indications of decreased cardiac output. The hemodynamic optimization strategy called stroke volume optimization might provide a proactive guide for clinicians to optimize a patient's status before late indications of a worsening condition occur. The evidence supporting use of the stroke volume optimization algorithm to treat hypovolemia is increasing. Many of the cardiac output monitor technologies today measure stroke volume, as well as the parameters that comprise stroke volume: preload, afterload, and contractility. PMID:25639574

  6. Leading among leaders: the dean in today's medical school.

    PubMed

    Daugherty, R M

    1998-06-01

    The magnitude and pace of change in the health care environment demand that medical schools change. Leading in a time of great change is difficult, and it is ironic that just when stability in leadership is most needed, the average tenure of deans is dropping. Indeed, the path to leadership in academic medicine is strewn with inherent ironies, paradoxes, and idiosyncrasies. For example, few people who become leaders in academic medicine aspire to, plan for, or seek training for leadership, yet leadership skills are essential to meet today's complex institutional demands. Also, most medical school deans were once medical students, and were selected and trained to be assertive, independent physicians, not to collaborate. For faculty, the medical school environment traditionally values individual autonomy and rewards individual achievement, not behavior that supports a larger community interest. Yet today's deans must be skilled at collaborative behavior, since they must have a vision for their schools and find ways to offer direction to the faculty and others to realize that vision. The author offers ideas about leadership and its development, and stresses that good leaders must above all curtail their egos in order to do what is best for their institutions. What a dean does as an individual is not nearly as important as what a dean enables others to do. The author also provides a checklist of dean's characteristics and responsibilities to help deans-to-be understand the job and current deans to think about how to succeed and thrive. He concluded by reiterating that the culture of individual faculty success based on individual entrepreneurism is passé. To operate in the new collaborative culture, today's successful dean must meld persuasion with educational statesmanship, always informed by a vision of how the school can prosper and serve.

    Plagued by difficult economic times, many radiology managers may find themselves faced with ethical dilemmas surrounding ongoing organizational pressures to maintain high levels of productivity with restricted resources. This often times tests the level of moral resilience and corporate social consciousness of even the most experienced radiology professionals. A study was conducted to determine what Corporate Social Responsibility (CSR) orientation and viewpoint future radiology professionals may have. The results of the study indicate that these study participants may initially consider patient care more important than profit maximization. Study results indicate that these specific future radiology professionals will not need laws, legal sanctions, and intensified rules to force them to act ethically. However,they may need ongoing training as to the necessity of profit maximization if they seek the highest quality of care possible for their patients. PMID:21366145

Document standards, including those which facilitate the contents of a massage, such as DICOM SR and HL7 CDA. And terminology standards, including those which facilitate the understanding of concepts of the domain. Since, the harmonization between different standards are important to meet interoperability, so the more effort is needed to conduct harmonization between tele-radiology standards and other domain.

    Planning and preparation in advance for radiological emergencies can help to minimise potential public health and environmental threats if and when an actual emergency occurs. During the planning process, emergency response organisations think through how they would respond to each type of incident and the resources that will be needed. In Malaysia, planning, preparation for and response to radiological emergencies involve many parties. In the event of a radiological emergency and if it is considered a disaster, the National Security Council, the Atomic Energy Licensing Board and the Malaysian Nuclear Agency (Nuclear Malaysia) will work together with other federal agencies, state and local governments, first responders and international organisations to monitor the situation, contain the release, and clean up the contaminated site. Throughout the response, these agencies use their protective action guidelines. This paper discusses Malaysian preparedness for, and response to, any potential radiological emergency. PMID:21729940

The tamper detector typically includes a network of sealed tubing that spans at least a portion of the access porthole. There is an opening in the network of sealed tubing that is large enough for passage therethrough of the radiological source and small enough to prevent passage therethrough of the associated shipping cask. Generally a gas source connector is provided for establishing a gas pressure in the network of sealed tubing, and a pressure drop sensor is provided for detecting a drop in the gas pressure below a preset value.

    The authors examined 11 patients with fibrous dysplasia of the skull pointing out its radiologic features and preferential sites. Conventional radiology, CT and MR imaging were used. As for conventional radiology, tangential scans which of great value to depict the most typical morphologic patterns. Lesions of the skull base were most frequent in the sphenoid (7 of 11 cases), where 5 of 7 exhibited a sclerotic pattern. Bone changes in the skull vault were: mixed (3 cases), pagetoid (2 cases), "ground glass" (1 case) and lytic (1 case): none of these cases was of the sclerotic type. A typical feature of vault lesions was the widening of diploic space associated with expansion of the outer bone and integrity of the inner bone. Radiologic findings, often associated with suggestive clinical manifestations, always allowed a diagnostic hypothesis; histopathologic confirmation was needed only in a few cases (4 of 11 patients).

  19. Leadership and management in quality radiology

    PubMed Central

    2007-01-01

    The practice of medical imaging and interventional radiology are undergoing rapid change in recent years due to technological advances, workload escalation, workforce shortage, globalisation, corporatisation, commercialisation and commoditisation of healthcare. These professional and economical changes are challenging the established norm but may bring new opportunities. There is an increasing awareness of and interest in the quality of care and patient safety in medical imaging and interventional radiology. Among the professional organisations, a range of quality systems are available to address individual, facility and system needs. To manage the limited resources successfully, radiologists and professional organisations must be leaders and champion for the cause of quality care and patient safety. Close collaboration with other stakeholders towards the development and management of proactive, long-term, system-based strategies and infrastructures will underpin a sustainable future in quality radiology. The International Radiology Quality Network can play a useful facilitating role in this worthwhile but challenging endeavour. PMID:21614284

    The multilingual search engine ARRS GoldMiner Global was created to facilitate broad international access to a richly indexed collection of more than 200,000 radiologic images. Images are indexed according to key-words and medical concepts that appear in the unstructured text of their English-language image captions. GoldMiner Global exploits the Unicode standard, which allows the accurate representation of characters and ideographs from virtually any language and which supports both left-to-right and right-to-left text directions. The user interface supports queries in Arabic, Chinese, French, German, Italian, Japanese, Korean, Portuguese, Russian, or Spanish. GoldMiner Global incorporates an interface to the United States National Library of Medicine that translates queries into English-language Medical Subject Headings (MeSH) terms. The translated MeSH terms are then used to search the image index and retrieve relevant images. Explanatory text, pull-down menu choices, and navigational guides are displayed in the selected language; search results are displayed in English. GoldMiner Global is freely available on the World Wide Web. PMID:19019997

    In 1989, Pacific Northwest National Laboratory developed a program, for the U.S. Department of Energy, to involve local citizens in environmental surveillance at the Hanford Site. The Community-Operated Environmental Surveillance Program was patterned after similar community-involvement efforts at the Nevada Test Site and the Three Mile Island nuclear facility. Its purpose is to increase the flow of information to the public, thereby enhancing the public's awareness and understanding of surveillance activities. The program consists of two components: radiological air monitoring at nine offsite locations and agricultural product sampling at selected locations near the site. At each air-monitoring station, two local school teachers collect air particulate samples and operate equipment to monitor ambient radiation levels. Atmospheric tritium samples (as water vapor) are also collected at some locations. Four of the air-monitoring stations include large, colorful informational displays for public viewing. These displays provide details on station equipment, sample types, and sampling purposes. Instruments in the displays also monitor, record, and show real-time ambient radiation readings (measured with a pressurized ionization chamber) and meteorological conditions. Agricultural products, grown primarily by middle-school-aged students, are obtained from areas downwind of the site. Following analysis of these samples, environmental surveillance staff visit the schools to discuss the results with the students and their teachers. The data collected by these air and agricultural sampling efforts are summarized with other routinely collected sitewide surveillance data and reported annually in the Hanford Site environmental report.

    The activity concentrations and absorbed gamma dose rates due to primordial radionuclides and (137)Cs have been ascertained in 222 soil samples in 18 counties of the Trabzon province of Turkey using a HPGe detector. The mean activity concentrations of (238)U, (232)Th, (40)K and (137)Cs in soil samples were 41, 35, 437 and 21 Bq kg(-1), respectively. Based on the measured concentrations of these radionuclides, the mean absorbed gamma dose in air was calculated as 59 nGy h(-1) and hence, the mean annual effective dose due to terrestrial gamma radiation was calculated as 72 μSv y(-1). In addition, outdoor in situ gamma dose rate (D) measurements were performed in the same 222 locations using a portable NaI detector and the annual effective dose was calculated to be 66 μSv y(-1) from these results. The results presented in this study are compared with other parts of Turkey. Radiological maps of the Trabzon province were composed using the results obtained from the study. PMID:21382657

    The early prediction of the response to treatment using quantitative imaging holds great promise for streamlining the development, assessment, approval and personalization of new therapies. However, to realize this potential, quantitative radiology needs to develop an understanding of several limitations that might hinder the application of quantitation tools and techniques. Among these limitations, the fidelity of the display device used to interpret the image data is a significant factor that affects the accuracy and precision of quantitative visual tasks, particularly those involving large, volumetric, multi-dimensional and multi-modality image sets. This paper reviews several aspects of display performance and display image quality that are likely to contribute negatively to the robustness of quantitative imaging methods. Display characteristics that will be addressed include the grayscale and color performance of different classes of display devices, the angular distribution of the emissions of liquid crystal technologies, and the temporal response for stack mode viewing. The paper will also summarize current efforts for the metrology, standardization and image quality assessment methods for display devices.: PMID:24980719

    Version 03 RSAC-6.2 can be used to model complex accidents and radiological consequences to individuals from the release of radionuclides to the atmosphere. A user can generate a fission product inventory; decay and ingrow the inventory during transport through processes, facilities, and the environment; model the downwind dispersion of the activity; and calculate doses to downwind individuals. Doses are calculated through the inhalation, immersion, ground surface and ingestion pathways. New to RSAC-6.2 are the abilitiesmore » to calculate inhalation from release to a room, inhalation from resuspension of activities, and a new model for dry deposition. Doses can now be calculated as close as 10 meters from the release point. RSAC-6.2 has been subjected to extensive independent verification and validation for use in performing safety-related dose calculations to support safety analysis reports. WinRP 2.0, a windows based overlay to RSAC-6.2, assists users in creating and running RSAC-6.2 input files. RSAC-6, Rev. 6.2 (03/11/02) corrects an earlier issue with RSAC-6, compiled with F77L-EM/32 Fortran 77 Version 5.10, which would not allow the executable to run with XP or VISTA Windows operating systems.

  6. Rumors and gossip in radiology.

    1997-01-01

    Rumors and gossip have long been popular topics in literature. Social scientists have even studied the topic and defined four main types of rumor: wish rumors; fear or bogey rumors; wedge-driving or aggressive rumors; and anticipatory rumors. In general, people believe rumor and gossip are synonymous. Rumormongering--the spreading of rumors--occurs among all cultures and types of people. Both men and women gossip and women's gossip is not more vindicative than men's, as is often thought. With such new means of communication as the Internet, transmitting rumor is possible beyond the traditional oral and written forms. Rumor is spread in both the higher and lower levels of an organization. Typically, disproving a rumor is more difficult than proving a rumor. The financial impact of a rumor must be considered also. If people believe, for example, that a radiology department does not have its act together or offers poor customer service, the department may lose revenue because people have lost confidence in it. Originally, the word gossip had positive implications. It referred to a family friend or the woman who delivered a child and announced the event to the community. Because well-intentioned gossip often turns into a damaging story, various approaches for stopping rumors have been identified. They include analyzing the grapevine, identifying the habitual spreaders of rumor and keeping employees informed. In most cases, a person of authority who provides facts can stop or at least slow down rumors spreading at the employee level. PMID:10175327

    The substantial debt load of new dentists is part of the recent trend toward beginning practice as an associate, in a postdoctoral general dentistry program, or in the military. Other reasons include an opportunity to build clinical speed, learning practice management skills, and earning a guaranteed income. While today's new dentists value the same goals of quality, service, and autonomy that motivate established practitioners, they bring new dimensions to the profession. Diversity and a desire for a balanced lifestyle (among both men and women) affect practice decisions and participation in organized dentistry. The new dentist will look for flexibility and responsiveness to personal and social challenges. PMID:16623129

    Modern radiology is at the forefront of technological progress in medicine, a position that often places unique challenges on its professional character. This article uses "Medical Professionalism in the New Millennium: A Physician Charter," a document published in 2002 and endorsed by several major radiology organizations, as a lens for exploring professional challenges in modern radiology. The three main tenets of the Charter emphasize patient welfare, patient autonomy, and the reduction of disparities in health care distribution. This article reviews the ways in which modern technology and financial structures potentially create stressors on professionalism in radiology, while highlighting the opportunities they provide for radiologists seeking to fulfill the professional goals articulated in the Charter. Picture archiving and communication systems (PACS) and voice recognition systems have transformed the speed of radiology and enhanced the ability of radiologists to improve patient care but also have brought new tensions to the workplace. Although teleradiology may improve global access to radiologists, it may also promote the commoditization of radiology, which diminishes the professional stature of radiologists. Social media and patient portals provide radiologists with new forums for interacting with the public and patients, potentially promoting patient welfare. However, patient privacy and autonomy are important considerations. Finally, modern financial structures provide radiologists with both entrepreneurial opportunities as well as the temptation for unprofessional conduct. Each of these advances carries the potential for professional growth while testing the professional stature of radiology. By considering the risks and benefits of emerging technologies in the modern radiology world, radiologists can chart an ethical and professional future path. PMID:26466185

    There is a growing need for introducing objective structured clinical examination (OSCE) as a part of radiology practical examinations in India. OSCE is an established, reliable, and effective multistation test for the assessment of practical professional skills in an objective and a transparent manner. In India, it has been successfully initiated and implemented in specialties like pediatrics, ophthalmology, and otolaryngology. Each OSCE station needs to have a pre-agreed “key-list” that contains a list of objective steps prepared for uniformly assessing the tasks given to students. Broadly, OSCE stations are classified as “manned” or “unmanned” stations. These stations may include procedure or pictorial or theory stations with clinical oriented contents. This article is one of a series of measures to initiate OSCE in radiology; it analyzes the attributes of OSCE stations and outlines the steps for implementing OSCE. Furthermore, important issues like the advantages of OSCE, its limitations, a strengths, weaknesses, opportunities, and threats (SWOT) analysis, and the timing of introduction of OSCE in radiology are also covered. The OSCE format in radiology and its stations needs to be validated, certified, and finalized before its use in examinations. This will need active participation and contribution from the academic radiology fraternity and inputs from faculty members of leading teaching institutions. Many workshops/meetings need to be conducted. Indeed, these collaborative measures will effectively sensitize universities, examiners, organizers, faculty, and students across India to OSCE and help successfully usher in this new format in radiology practical examinations.

    Recently the radical critique has been revived of medicine teaching developed some fifty years ago by G.A. Maccacaro with special focus on Italy. He maintained that a dominating biological perspective obscured all social dimensions of health and disease, educating doctors poorly equipped to grasp the practical relevance of social determinants of diseases and to correctly perceive their own role in society. In fifty years, many aspects of the practice of medicine have however changed: how such changes relate to the current teaching of medicine? Three key developments have taken place. First, separate specialties and subspecialties have multiplied at fast pace, and teaching has usually favoured this increasing fragmentation. Second, in actual practice doctors need to overcome disciplinary segmentation and collaborate, often to a substantial extent: little trace of how best to implement this is present in academic teaching. Third evidence-based medicine and guidelines for preventive, diagnostic and therapeutic interventions have become common currency in medicine: teaching of these topics is, notably in Italy, in general weak, leaving future doctors unprepared to a critical understanding and use of evidence-based medicine and guidelines in the daily practice. Substantial changes in medical teaching appear needed today no less than fifty years ago, but they can only start from a recognition of medicine as it stands today rather than fifty years ago.

    Osteoporosis accounts for about 3 % of total European health-care spending. The low proportion of costs for the pharmacological prevention of osteoporotic fracture means that it is highly cost saving, especially in patient with severe osteoporosis or patients who cannot take certain osteoporosis medications due to issues of contraindications or tolerability. Following recent regulatory changes, strontium ranelate is now indicated in patients with severe osteoporosis for whom treatment with other osteoporosis treatments is not possible, and without contraindications including uncontrolled hypertension, established, current or past history of ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease. We review here today's evidence for the safety and efficacy of strontium ranelate. The efficacy of strontium ranelate in patients complying with the new prescribing information (i.e. severe osteoporosis without contraindications) has been explored in a multivariate analysis of clinical trial data, which concluded that the antifracture efficacy of strontium ranelate is maintained in patients with severe osteoporosis without contraindications and also demonstrated how the new target population mitigates risk. Strontium ranelate is therefore an important alternative in today's management of osteoporosis, with a positive benefit-risk balance, provided that the revised indication and contraindications are followed and cardiovascular risk is monitored. The bone community should be reassured that there remain viable alternatives in patients in whom treatment with other agents is not possible and protection against the debilitating effects of fracture is still feasible in patients with severe osteoporosis.

    The U.S. Department of Energy (DOE) provides technical support to the requesting federal agency such as the Federal Bureau of Investigation, Department of Defense, the National Space and Aeronautics and Space Administration (NASA), or a state agency to address the radiological consequences of an event. These activities include measures to alleviate damage, loss, hardship, or suffering caused by the incident; protect public health and safety; restore essential government services; and provide emergency assistance to those affected. Scheduled to launch in the fall of 2009, Mars Science Laboratory is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet. Mars Science Laboratory is a rover that will assess whether Mars ever was, or is still today, an environment able to support microbial life. In other words, its mission is to determine the planet's "habitability." The Mars Science Laboratory rover will carry a radioisotope power system that generates electricity from the heat of plutonium's radioactive decay. This power source gives the mission an operating lifespan on Mars' surface of a full Martian year (687 Earth days) or more, while also providing significantly greater mobility and operational flexibility, enhanced science payload capability, and exploration of a much larger range of latitudes and altitudes than was possible on previous missions to Mars. National Security Technologies, LLC (NSTec), based in Las Vegas, Nevada, will support the DOE in its role for managing the overall radiological contingency planning support effort. This paper will focus on new technologies that NSTec is developing to enhance the overall response capability that would be required for a highly unlikely anomaly. This paper presents recent advances in collecting and collating data transmitted from deployed teams and sensors. NSTec is responsible to prepare the contingency planning for a range of areas from monitoring and assessment

    The threat of terrorist events on domestic soil remains an ever-present risk. Despite the notoriety of unconventional weapons, the mainstay in the armament of the terrorist organization is the conventional explosive. Conventional explosives are easily weaponized and readily obtainable, and the recipes are widely available over the Internet. According to the US Department of State and the Federal Bureau of Investigation, over one half of the global terrorist events involve explosions, averaging two explosive events per day worldwide in 2005 (Terrorism Research Center. Available at www.terrorism.com. Accessed April 1, 2007). The Future of Emergency Care in the United States Health System: Emergency Medical Services at the Crossroads, published by the Institute of Medicine, states that explosions were the most common cause of injuries associated with terrorism (Institute of Medicine Report: The Future of Emergency Care in the United States Health System: Emergency Medical Services at the Crossroads. Washington DC: National Academic Press, 2007). Explosive events have the potential to inflict numerous casualties with multiple injuries. The complexity of this scenario is exacerbated by the fact that few providers or medical facilities have experience with mass casualty events in which human and material resources can be rapidly overwhelmed. Care of explosive-related injury is based on same principles as that of standard trauma management paradigms. The basic difference between explosion-related injury and other injury mechanisms are the number of patients and multiplicity of injuries, which require a higher allocation of resources. With this caveat, the appropriate utilization of radiology resources has the potential to impact in-hospital diagnosis and triage and is an essential element in optimizing the management of the explosive-injured patients.

    Available in abstract form only. Full text of publication follows: In the Netherlands there are some 200 producers of radioactive waste. Most of them generate only small volumes of low and medium level waste. These small volumes however cover a wide range of waste forms: solids, liquids of all nature, slurries, etc. Because of the resulting wide spectrum of radiological and chemical contaminations, a certain amount of flexibility is required in both solid and liquid waste treatment. In addition, the Nuclear Energy Act license requires a five yearly evaluation of the waste processing installation with respect to the Best Practicable Technologies. The bulk of the solid waste are compacted, conditioned as cemented packages and stored for at least hundred years. The low-level liquid waste is treated batch-wise as the volumes of liquid waste are too small to operate a continuous system. Moreover, batch-wise processing enables more flexibility. Discharge of treated water is bounded by concentration limits of chemicals and total activity per nuclide. Evaluation of the installation showed that the radiological constraints provide a larger degree of freedom to discharge, and the waste water treatment can effectively meet the required limits. The limits of concentration of chemicals are more restrictive. The liquid waste often has more chemical contamination than radiological. This paper describes the evaluation of the waste water treatment. (authors)

    Experience and knowledge gained from ongoing maintenance of Space Shuttle Flight Software and new development projects including Cockpit Avionics Upgrade are applied to projected needs of the National Space Exploration Vision through Spiral 2. Lessons learned from these current activities are applied to create a sustainable, reliable model for development of critical software to support Project Constellation. This presentation introduces the technologies, methodologies, and infrastructure needed to produce and sustain high quality software. It will propose what is needed to support a Vision for Space Exploration that places demands on the innovation and productivity needed to support future space exploration. The technologies in use today within FSW development include tools that provide requirements tracking, integrated change management, modeling and simulation software. Specific challenges that have been met include the introduction and integration of Commercial Off the Shelf (COTS) Real Time Operating System for critical functions. Though technology prediction has proved to be imprecise, Project Constellation requirements will need continued integration of new technology with evolving methodologies and changing project infrastructure. Targets for continued technology investment are integrated health monitoring and management, self healing software, standard payload interfaces, autonomous operation, and improvements in training. Emulation of the target hardware will also allow significant streamlining of development and testing. The methodologies in use today for FSW development are object oriented UML design, iterative development using independent components, as well as rapid prototyping . In addition, Lean Six Sigma and CMMI play a critical role in the quality and efficiency of the workforce processes.

  9. Crosscheck Principle in Pediatric Audiology Today: A 40-Year Perspective.

    PubMed

    Hall, James W

    2016-09-01

    The crosscheck principle is just as important in pediatric audiology as it was when first described 40 years ago. That is, no auditory test result should be accepted and used in the diagnosis of hearing loss until it is confirmed or crosschecked by one or more independent measures. Exclusive reliance on only one or two tests, even objective auditory measures, may result in a auditory diagnosis that is not clear or perhaps incorrect. On the other hand, close and careful analysis of findings for a test battery consisting of objective procedures and behavioral tests whenever feasible usually leads to prompt and accurate diagnosis of auditory dysfunction. This paper provides a concise review of the crosscheck principle from its introduction to its clinical application today. The review concludes with a description of a modern test battery for pediatric hearing assessment that supplements traditional behavioral tests with a variety of independent objective procedures including aural immittance measures, otoacoustic emissions, and auditory evoked responses.

    The current system of medical malpractice does a poor job of serving the best interests of physicians or patients. Economic and societal forces are shifting the nature of health care from the individual physician to a system of health care professionals, characterized by accountable care organizations. In particular, more physicians are employed, quality and outcomes are routinely measured, and reimbursement is moving to value-based purchasing. Medical malpractice likewise needs to transition to a new model that is consistent with the modern era of patient-centered care. Collective accountability, the concept that patient care is the responsibility of all the members of the health care organization, requires malpractice reform that reflects a systems-based practice of medicine. Enterprise liability, coupled with medical error communication and resolution programs, provides the legal framework necessary for the patient-centered practice of medicine in today's environment.

    Polyurethanes are the only class of polymers that display thermoplastic, elastomeric, and thermoset behavior depending on their chemical and morphological makeup. In addition to compact polyurethanes, foamed variations in particular are very widespread, and they achieve their targeted properties at very low weights. The simple production of sandwich structures and material composites in a single processing step is a key advantage of polyurethane technology. The requirement of energy and resource efficiency increasingly demands lightweight structures. Polyurethanes can serve this requirement by acting as matrix materials or as flexible adhesives for composites. Polyurethanes are indispensable when it comes to high-quality decorative coatings or maintaining the value of numerous objects. They are extremely adaptable and sustainable problem solvers for today's challenges facing our society, all of which impose special demands on materials. PMID:23893938

    The 20-year period of 1948-1968, during which Andrei D Sakharov crucially contributed to the creation of the Soviet nuclear shield, was followed by the same length of time from 1969 to 1989, when he was no less patriotic in his human rights activities and in his efforts to save humankind from self-destruction in a thermonuclear war. When free of these commitments, Sakharov always turned to his favorite pastime, theoretical physics, where, working on the 'roadside' (to use his own words), he obtained a number of results of continuing importance. Some of these are described in this talk, as are Sakharov's actions and approaches, highly nontrivial and still relevant today, to solving the problems of major public concern.

    2013-03-01

    In 1963, the first issue of the journal Psychotherapy appeared. Responding to findings reported in a previous publication by Eysenck (1952), Strupp wrote of the "staggering research problems" (p. 2) confronting the field and the necessity of conducting "properly planned an executed experimental studies" to resolve questions about the process and outcome of psychotherapy. Today, both the efficacy and effectiveness of psychotherapy has been well established. Despite the consistent findings substantiating the field's worth, a significant question remains the subject of debate: how does psychotherapy work? On this subject, debate continues to divide the profession. In this paper, a "way out" is proposed informed by research on the therapist's contribution to treatment outcome and findings from studies on the acquisition of expertise. PMID:23505984

    In today's consumer market, there are many different light bulbs that claim to produce `natural' light. In my research, I both quantitatively and qualitatively analyzed this claim. First, utilizing a spectroscope, I compared the spectra emitted by different brands and types of compact fluorescent light (CFL) bulbs to the spectra emitted by the Sun. Once the bulbs were quantitatively analyzed, I proceeded to qualitatively analyze them by exposing subjects to the different bulbs. The subjects were asked to rate the quality of color in different pictures illuminated by each type of CFL. From these tests, I was able to determine the ``best'' CFL bulbs, and conclude whether the health risks associated with CFL bulbs outweigh the cost savings, longevity of the bulbs, and/or quality of light benefits.

    The Site Generated Radiological Waste Handling System handles radioactive waste products that are generated at the geologic repository operations area. The waste is collected, treated if required, packaged for shipment, and shipped to a disposal site. Waste streams include low-level waste (LLW) in solid and liquid forms, as-well-as mixed waste that contains hazardous and radioactive constituents. Liquid LLW is segregated into two streams, non-recyclable and recyclable. The non-recyclable stream may contain detergents or other non-hazardous cleaning agents and is packaged for shipment. The recyclable stream is treated to recycle a large portion of the water while the remaining concentrated waste is packaged for shipment; this greatly reduces the volume of waste requiring disposal. There will be no liquid LLW discharge. Solid LLW consists of wet solids such as ion exchange resins and filter cartridges, as-well-as dry active waste such as tools, protective clothing, and poly bags. Solids will be sorted, volume reduced, and packaged for shipment. The generation of mixed waste at the Monitored Geologic Repository (MGR) is not planned; however, if it does come into existence, it will be collected and packaged for disposal at its point of occurrence, temporarily staged, then shipped to government-approved off-site facilities for disposal. The Site Generated Radiological Waste Handling System has equipment located in both the Waste Treatment Building (WTB) and in the Waste Handling Building (WHB). All types of liquid and solid LLW are processed in the WTB, while wet solid waste from the Pool Water Treatment and Cooling System is packaged where received in the WHB. There is no installed hardware for mixed waste. The Site Generated Radiological Waste Handling System receives waste from locations where water is used for decontamination functions. In most cases the water is piped back to the WTB for processing. The WTB and WHB provide staging areas for storing and shipping LLW

    2005-06-01

    Recent and rapid increases in the utilization of diagnostic imaging have not been matched by concomitant additions to the supply of radiologists and radiology technologists. One proposal to alleviate an expected worsening of this emerging workforce crisis is to create a new job category, the radiology assistant (RA), encompassing a roster of enhanced capabilities that would allow the radiologists to divest themselves of some of their non-interpretative duties with respect to the performance of imaging tests. Through the collaborative efforts of the American College of Radiology and the American Society of Radiology Technologists a nationally recognized, baccalaureate-level curriculum has been designed for the training of RAs. A centerpiece of the curriculum is instruction in fluoroscopy. However, examinations of the GI tract by fluoroscopy are rapidly declining in frequency, raising doubt about the enhanced value an RA would bring to a radiology practice in the near future and worries about encroachment on the range of radiologists' responsibilities over the long term.

    1999-02-01

    This document provides a report of an analysis of the Radiological Control Program through the fourth quarter of Calendar Year (CY-98) and is the annual report for the Idaho National Engineering and Environmental Laboratory (INEEL). This Performance Indicator Report is provided in accordance with Article 133 of the INEEL Radiological Control Manual. The INEEL collective occupational radiation deep dose is 63.034 person-rem year to date, compared to a goal of 83.1 person-rem. During the fourth quarter, all areas experienced deletions of work resulting from the Maintenance Stand Down. This reduction in work is a primary factor in the difference in the year end dose and the ALARA goal. The work will be completed during CY-99. Beginning in CY-98, a numeric Radiological Performance Index (RPI) is being used to compare radiological performance. The RPI takes into consideration frequency and severity of events such as skin contaminations, clothing contaminations, spills, exposures to radiation exceeding limits, and positive internal dose. The RPI measures the cost of these events in cents per hour of radiological work performed. To make the RPI meaningful, tables have been prepared to show the facility that contributes to the values used. The data are compared on a quarterly basis to the prior year to show measurable performance.

    The International Commission on Radiological Protection (ICRP) has established Task Group 94 under Committee 4 to develop a report on the ethical foundations of the system of radiological protection. The aim of this report is to consolidate the basis of ICRP recommendations, to improve understanding of the system, and to provide a basis for communication on radiation risk and its perception. Through a series of workshops organised by the Commission in cooperation with the International Radiation Protection Association and its associate societies involving radiological protection professionals and specialists of ethics around the world, Task Group 94 has identified the key ethical and social values underpinning the system of radiological protection. The purpose of eliciting the ethical principles and values of the radiological protection system is not only to clarify the rationale for recommendations made by the Commission, but also to assist in discussions related to its practical implementation. A clear understanding of the ethical principles will help resolve dilemmas caused by potential conflicts in actions that might be considered, or decisions that must be made. PMID:26980798

    In today's extremely competitive economic environment, the quality management processes used by industrial companies have become commonplace at hospitals and are proving successful in improving quality and controlling costs. Continuous quality improvement (CQI) methods provide a relatively new way, compared with quality assurance (QA) and quality control (QC) methods, to improve the quality of health care. Continuous quality improvement should be considered a philosophy rather than simply a methodology; it assumes no endpoints in improvement efforts and does not attempt to replace the older concepts of QA and QC but rather to reap their benefits and take them to a higher conceptual level. Continuous quality improvement has 4 foci: (1) to determine and meet the needs of patients and customers, (2) to approach quality improvement holistically on the basis of the identification of the underlying cause of poor performance, (3) to apply fact-based management and scientific methodology, and (4) to empower its practitioners to improve quality on a daily basis. Health care institutions and radiology departments use a variety of CQI systems or models, including the model of the Joint Commission on Accreditation of Healthcare Organizations, the Six Sigma model, and the Model for Business Excellence of the European Foundation for Quality Management. The International Organization for Standardization 9000, which creates a suitable organizational environment for the implementation of a CQI system, can be considered an effective QA and QC method.

    Professionalism and ethics are difficult to define, and it is often a case of "you know it when you see it." In recent years, there have been calls to renew the focus on professionalism and ethics and their teaching in the medical and allied professions, part precipitated by a perceived and probably real decline in doctors' professional values. Medical professionalism has evolved markedly in the last couple of centuries and continues to change today at a rapid pace, spurred by technological advances and generational change. The reasons to promote medical professionalism include regulatory requirements, aligning our professions' outcomes and behaviors, and the moral imperative that being professional is the right thing to do. Radiologists should emphasize, model, and teach professionalism to our colleagues, allied personnel, and trainees whenever opportunity permits. Medical students now receive teaching in professionalism and ethics throughout their training, and there is a need to continue training formally and informally during residency training. Faculty or those charged with teaching professionalism will need to first understand what constitutes medical professionalism, and here we attempt to define and outline what professionalism looks like in practice. The article concludes with a summary of the opportunities within radiology practice, with examples, for us to exhibit professional actions, values, and ideas. PMID:26971041

    Interventional radiology is a relatively new speciality and may be referred to as "image-guided surgery without a scalpel". Training and accreditation bodies regard interventional radiology training as being "different" from general radiology because of the additional need for dexterity and clinical acumen. Due to the multidimensional role of an interventional radiologist, a practitioner in this discipline must have a number of the competencies of anesthetists, surgeons, and radiologists. The attributes required of an interventional radiologist are akin to those required of a surgeon. This paper gives an overview of the skills required to be a competent interventional radiologist along with a succinct introduction to methods of assessment of technical and non-technical skills.

    An estimated two thirds of the world's population is currently without access to diagnostic radiology services, and most of them live in resource-limited tropical regions with harsh environments. Most patients are diagnosed and treated in poorly equipped government-funded hospitals and clinics that have insufficiently trained staff and are barely operational. Any available imaging equipment is likely to be functioning suboptimally and be poorly maintained. The root of the problem is usually a lack of know-how and a quality culture, combined with insufficient basic equipment and infrastructure. Radiological imaging is an essential aspect of primary care and used in the critical diagnosis and management of trauma, tuberculosis, pneumonia, acquired immunodeficiency syndrome, cancer, and other respiratory and abdominal diseases. Considerations such as quality management and infrastructure, personnel, equipment, and radiation protection and safety are important to ensure the proper functioning and rational use of a diagnostic radiology facility in the tropics.

    2004-03-01

    The core principles of digital radiology were well developed by the end of the 1980 s. During the following decade tremendous improvements in computer technology enabled realization of those principles at an affordable cost. In this decade work can focus on highly distributed radiology in the context of the integrated health care enterprise. Over the same period computer networking has evolved from a relatively obscure field used by a small number of researchers across low-speed serial links to a pervasive technology that affects nearly all facets of society. Development directions in network technology will ultimately provide end-to-end data paths with speeds that match or exceed the speeds of data paths within the local network and even within workstations. This article describes key developments in Next Generation Networks, potential obstacles, and scenarios in which digital radiology can become a "killer app" that helps to drive deployment of new network infrastructure.

    2004-08-01

    Contracts between radiology groups and their physician members are often ambiguous. Key clauses may not be precise as to the intent of the contracting parties. For example, the requirements for a group member to achieve shareholder status may be discussed but not reduced to a written form. Other contract provisions, such as termination or noncompete clauses, may be subject to different interpretations. The ambiguities of these provisions often generate disparate expectations regarding the parties' obligations to one another. When this occurs, the results may vary from disappointment to litigation. This paper discusses the causes and consequences of common breaches of radiology contracts. The types of remedies that may be available to the parties of the contract are also enumerated, and case law is cited to illustrate the challenges that radiology groups and their members may encounter. Finally, alternative forms of dispute resolution are discussed. PMID:17411653

    The emergency management planning tool RISK-RDD was developed to aid emergency response planners and decision makers at all levels of government to better understand and prepare for potential problems related to a radiological release, especially those in urban areas. Radioactive release scenarios were studied by using the RISK-RDD radiological emergency management program. The scenarios were selected to investigate the key aspects of radiological risk management not always considered in emergency planning as a whole. These aspects include the evaluation of both aerosolized and non-aerosolized components of an atmospheric release, methods of release, acute and chronic human health risks, and the concomitant economic impacts as a function of the risk-based cleanup level.

    Varicocele is a fairly common condition in male individuals. Although a minor disease, it may cause infertility and testicular pain. Consequently, it has high health and social impact. Here we review the current status of interventional radiology of male varicocele. We describe the radiological anatomy of gonadal veins and the clinical aspects of male varicocele, particularly the physical examination, which includes a new clinical and ultrasound Doppler maneuver. The surgical and radiological treatment options are also described with the focus on retrograde and antegrade sclerotherapy, together with our long experience with these procedures. Last, we compare the outcomes, recurrence and persistence rates, complications, procedure time and cost-effectiveness of each method. It clearly emerges from this analysis that there is a need for randomized multicentre trials designed to compare the various surgical and percutaneous techniques, all of which are aimed at occlusion of the anterior pampiniform plexus.

  11. Advanced Neutron Source radiological design criteria

    SciTech Connect

    Westbrook, J.L.

    1995-08-01

    The operation of the proposed Advanced Neutron Source (ANS) facility will present a variety of radiological protection problems. Because it is desired to design and operate the ANS according to the applicable licensing standards of the Nuclear Regulatory Commission (NRC), it must be demonstrated that the ANS radiological design basis is consistent not only with state and Department of Energy (DOE) and other usual federal regulations, but also, so far as is practicable, with NRC regulations and with recommendations of such organizations as the Institute of Nuclear Power Operations (INPO) and the Electric Power Research Institute (EPRI). Also, the ANS radiological design basis is in general to be consistent with the recommendations of authoritative professional and scientific organizations, specifically the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). As regards radiological protection, the principal goals of DOE regulations and guidance are to keep occupational doses ALARA [as low as (is) reasonably achievable], given the current state of technology, costs, and operations requirements; to control and monitor contained and released radioactivity during normal operation to keep public doses and releases to the environment ALARA; and to limit doses to workers and the public during accident conditions. Meeting these general design objectives requires that principles of dose reduction and of radioactivity control by employed in the design, operation, modification, and decommissioning of the ANS. The purpose of this document is to provide basic radiological criteria for incorporating these principles into the design of the ANS. Operations, modification, and decommissioning will be covered only as they are affected by design.

    Direct volume rendering can visualize sampled 3D scalar data as a continuous medium, or extract features. However, it is generally slow. Furthermore, most algorithms for direct volume rendering have assumed rectilinear gridded data. This paper discusses methods for using direct volume rendering when the original volume is curvilinear, i.e. is divided into six-sided cells which are not necessarily equilateral hexahedra. One approach is to ray-cast such volumes directly. An alternative approach is to interpolate the sample volumes to a rectilinear grid, and use this regular volume for rendering. Advantages and disadvantages of the two approaches in terms of speed and image quality are explored.

    There is a divergence of opinion concerning the cricopharyngeal muscle defect commonly seen in the pharyngoesophageal area on barium esophagram. Some observers believe this defect is the result of neuromuscular dysfunction with the demonstration of the unrelaxed muscle bundle; however, others believe it is the result of actual hypertrophy of the cricopharyngeal muscle. Radiologic and pathologic study of 24 unselected autopsy cases revealed cricopharyngeal hypertrophy in 13 cases by radiologic criteria. Histologic examination revealed that the cricopharyngeal muscle thickness was uniformly greater in these cases than in the radiographically normal cases. The cricopharyngeal muscle defect is associated with actual hypertrophy of the cricopharyngeal muscle in many cases. PMID:6609574

    The shortage of deceased donor liver grafts led to the use of living donor liver transplant (LDLT). Patients who undergo LDLT have a higher risk of complications than those who undergo deceased donor liver transplantation (LT). Interventional radiology has acquired a key role in every LT program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplant. The aim of this paper is to review indications, diagnostic modalities, technical considerations, achievements and potential complications of interventional radiology procedures after LDLT.

    This editorial discusses a relatively new specialty in dental and medical field namely dentomaxillofacial radiology. As a relatively newborn specialty it is obvious that there is a long way to go before dentomaxillofacial radiology is commonly known and respected by the society. All over the world, assigned committees work on the development of the training curriculum, determination of scientific and physical standards for institutions offering specialty training and arrangement of dental codes for reimbursement issues. Furthermore, adjustment of educational, scientific and legal regulations and prospective benefits are expected to boost this specialty's attractiveness to colleagues' worldwide. PMID:26029350

    International Commission on Radiological Protection (ICRP), an independent international organization established in 1925, develops, maintains, and elaborates radiological protection standards, legislation, and guidelines. United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) provides scientific evidence. World Health Organization (WHO) and International Atomic Energy Agency (IAEA) utilise the ICRP recommendations to implement radiation protection in practice. Finally, radiation protection agencies in each country adopt the policies, and adapt them to each situation. In Korea, Nuclear Safety and Security Commission is the governmental body for nuclear safety regulation and Korea Institute of Nuclear Safety is a public organization for technical support and R&D in nuclear safety and radiation protection.
