Radiography In The Digital Age

Long overdue, this new work provides just the right focus and scope for the practice of radiography in this digital age, covering four entire courses in a typical radiography program. The entire emphasis of foundational physics has been adjusted in order to properly support the specific information on digital imaging that will follow. The paradigm shift in imaging terminology is reflected by the careful phrasing of concepts, accurate descriptions and clear illustrations throughout the book. There are over 700 illustrations, including meticulous color line drawings, numerous photographs and stark radiographs. The two chapters on digital image processing alone include 60 beautifully executed illustrations. Foundational chapters on math and basic physics maintain a focus on energy physics. Concepts supporting digital imaging (such as the interpretation of graphs supporting the understanding of histograms) are more thoroughly discussed. All discussion of electricity is limited to only those concepts which bear directly upon the production of x-rays in the x-ray tube. Following is a full discussion of the x-ray beam and its interactions within the patient, the production and characteristics of subject contrast, and an emphasis on the practical application of radiographic technique. This is conventional information, but the terminology and descriptions used have been adapted with great care to the digital environment. Eight chapters are devoted directly to digital imaging, providing extensive coverage of the physics of digital image capture, digital processing techniques, and the practical applications of both CR and DR. Image display systems are brought up to date with the physics of LCD screens and electronic images. PACS and medical imaging informatics are also covered. Chapters on Radiation Biology and Protection include an unflinching look at current issues and radiation protection in practice. The radiation biology is clearly presented with numerous lucid illustrations, and a balanced perspective on radiation and its medical use is developed. To reinforce mathematical concepts for the student, dozens of practice exercises are strategically dispersed throughout the chapters, with answer keys provided in the appendix. Extensive review questions at the end of each chapter give a thorough, comprehensive review of the material learned.

This Student Workbook for Radiography in the Digital Age is specifically designed for in-classroom use with the series PowerPoint Slides for Radiography in the Digital Age. Together with the textbook itself and the Instructor Resources CD, these products complete a full package of educational resources tailored for radiography courses in the Physics of Radiography, Principles of Imaging, Digital Image Acquisition and Display, and Radiation Biology and Protection. The Workbook is organized throughout in a concise "fill-in-the-blank" format, focusing on key words to reinforce students' retention of the material. The wording and sequencing of questions closely mirrors the PowerPoint Slide series for each course. This Workbook strikes a perfect balance between allowing the student to concentrate on the lecture by doing minimal writing while still challenging the student to participate in classroom learning. An effective "note-taking" tool, it also doubles as a reinforcement tool for homework and individual study.

The internet and related technologies have reconfigured every aspect of life, including mental health. Although the negative and positive effects of digital technology on mental health have been debated, all too often this has been done with much passion and few or no supporting data. This book brings together distinguished experts from around the world to review the evidence relating to this area.

The Instructor Resources for Radiography in the Digital Age, available on disc, includes the answer key for all chapter review questions and a bank of over 1500 multiple-choice questions for instructors’ use. It also includes 35 laboratory exercises, including 15 that demonstrate the applications of CR equipment. Supported by prominent medical physicists and documents from the American Association of Physicists in Medicine (AAPM), this textbook provides the most accurate information available to radiography educators in all the aspects of digital radiography.

This book is intended to provide medical radiography programs with an economical textbook that focuses on the practical aspects of digital radiography. In this new second edition by esteemed author Quinn B. Carroll and with content developed in close collaboration with the medical physics community and several reviewers, this is the most accurate information on digital imaging available. Terminology has been updated throughout the textbook to conform with the most recent revisions of the ASRT Radiography Curriculum Guide and the ARRT Radiography Content Specifications. Several new illustrations and helpful tables have been developed to clarify digital concepts. A new table, Operator Adjustments to Digital Image Qualities and Their Primary Controls, beautifully summarizes the effects of leveling, windowing, equalization, edge enhancement, smoothing and noise reduction, while related text reduces dozens of different manufacturers' terms to these basic operations in the table. Material on medical digital fluoroscopy and imaging informatics has been updated, with a continued emphasis on practical application and clinically useful information. Extensive support materials, including slides correlated to a student workbook, labs, comprehensive question banks and answer keys, have all been updated and improved.

The New York Times Science Bestseller from Robert Wachter, Modern Healthcare’s #1 Most Influential Physician-Executive in the US While modern medicine produces miracles, it also delivers care that is too often unsafe, unreliable, unsatisfying, and impossibly expensive. For the past few decades, technology has been touted as the cure for all of healthcare’s ills. But medicine stubbornly resisted computerization – until now. Over the past five years, thanks largely to billions of dollars in federal incentives, healthcare has finally gone digital. Yet once clinicians started using computers to actually deliver care, it dawned on them that something was deeply wrong. Why were doctors no longer making eye contact with their patients? How could one of America’s leading hospitals give a teenager a 39-fold overdose of a common antibiotic, despite a state-of-the-art computerized prescribing system? How could a recruiting ad for physicians tout the absence of an electronic medical record as a major selling point? Logically enough, we’ve pinned the problems on clunky software, flawed implementations, absurd regulations, and bad karma. It was all of those things, but it was also something far more complicated. And far more interesting . . . Written with a rare combination of compelling stories and hard-hitting analysis by one of the nation’s most thoughtful physicians, The Digital Doctor examines healthcare at the dawn of its computer age. It tackles the hard questions, from how technology is changing care at the bedside to whether government intervention has been useful or destructive. And it does so with clarity, insight, humor, and compassion. Ultimately, it is a hopeful story. "We need to recognize that computers in healthcare don’t simply replace my doctor’s scrawl with Helvetica 12," writes the author Dr. Robert Wachter. "Instead, they transform the work, the people who do it, and their relationships with each other and with patients. . . . Sure, we should have thought of this sooner. But it’s not too late to get it right." This riveting book offers the prescription for getting it right, making it essential reading for everyone – patient and provider alike – who cares about our healthcare system.

This helpful book, written specifically for radiographers, nurse practitioners and radiographer practitioners, can be used as a revision aid or study guide or to help prepare for an assessment. The first chapter, on non-accidental injury (NAI), is written from three different perspectives: that of a nurse practitioner with an interest in paediatrics; a social worker specialising in children; and a paediatric team leader radiographer, who discusses the skeletal survey. This is followed by a brief description of different types of paediatric fractures, with examples. The next chapter looks at the pathway for the limping child, followed by a series of paediatric trauma cases, on which the reader is asked to write reports. Karen Sakthivel-Wainford has concentrated on the areas of paediatric trauma that are most commonly presented to an emergency department or minor injuries unit. This edition includes 125 cases in total, with 25 new cases focusing on areas (such as the elbow) that practitioners find difficult to interpret. Contents include: • Introduction • Non-accidental injury • Introduction to paediatric fractures • Overview of the limping child • Wrist and hand trauma • Elbow and forearm trauma • Shoulder trauma • Ankle and foot trauma • Knee and tibia/fibula trauma • Pelvis and hip trauma • Spine, skull and facial trauma • A selection of cases
