This is the second edition of a well-received book that enriches the understanding of radiographers and radiologic technologists across the globe, and is designed to meet the needs of courses (units) on radiographic imaging equipment, procedures, production, and exposure. The book also serves as a supplement for courses that address digital imaging techniques, such as radiologic physics, radiographic equipment and quality control. In a broader sense, the purpose of the book is to meet readers’ needs in connection with the change from film-based imaging to film-less or digital imaging; today, all radiographic imaging worldwide is based on digital imaging technologies. The book covers a wide range of topics to address the needs of members of various professional radiologic technology associations, such as the American Society of Radiologic Technologists, the Canadian Association of Medical Radiation Technologists, the College of Radiographers in the UK, and the Australian and New Zealand Societies for Radiographers.

Practical and comprehensive, Digital Radiography and PACS offers up-to-date coverage of the latest digital imaging systems, including computed radiography (CR), digital radiography (DR), and PACS. Throughout, you'll find concise, step-by-step image acquisition guidelines, as well as detailed exposure guidelines and quality control practices to help you obtain the best possible radiographs. Tips on acquiring, processing, and producing clear radiographic images using the latest digital radiographic technologies. Working with CR/DR quality workstations, including advanced image processing and manipulation functions. Complete coverage of PACS workstations, archiving solutions, and system architectures. The most effective techniques for digitizing film, printing images, and preparing image files. Comprehensive quality control and management guidelines for PACS, CR, and DR. Book jacket.

Digital radiography is a general term describing any projection radiological system in which the image exists in digital form at some stage between acquisition and viewing. In an earlier form, radiographic films were dig itized in an attempt to enhance and redisplay information of interest. The field has evolved to its current state, in which X-ray signals are detected electronically, converted to digital form, and processed prior to being recorded and displayed. A primary goal of digital radiography is the re moval of interfering effects from secondary structures in an image, so that clinically significant details can be displayed with enhanced visibility. The achievement of this goal involves many parameters, including con trast agents, subtraction techniques, processing techniques, filtering tech niques, system noise, and quantitative aspects. It is the purpose of this book to present material by noted individuals in the field covering several of the above topics.

Digital Radiography: An Introduction for Technologists, presents the physical principles and technical description of digital radiography imaging systems and associated technologies. This book functions as both a primary source for introductory digital imaging courses and as a reference for radiologic technologists and other imaging personnel. The book begins by exploring the many digital image acquisition imaging modalities such as computed radiography (CR), flat-panel digital radiography, digital fluoroscopy, and digital mammography systems in detail, followed by an outline of the essential elements of digital image processing. Associated technologies such as picture archiving and communication systems (PACS) and medical imaging informatics (MII) are also outlined. Finally, the book concludes with a description of quality control procedures for digital radiography.

Comprehensive medical imaging physics notes aimed at those sitting the first FRCR physics exam in the UK and covering the scope of the Royal College of Radiologists syllabus. Written by Radiologists, the notes are concise and clearly organised with 100's of beautiful diagrams to aid understanding. The notes cover all of radiology physics, including basic science, x-ray imaging, CT, ultrasound, MRI, molecular imaging, and radiation dosimetry, protection and legislation. Although aimed at UK radiology trainees, it is also suitable for international residents taking similar examinations, postgraduate medical physics students and radiographers. The notes provide an excellent overview for anyone interested in the physics of radiology or just refreshing their knowledge. This third edition includes updates to reflect new legislation and many new illustrations, added sections, and removal of content no longer relevent to the FRCR physics exam. This edition has gone through strict critique and evaluation by physicists and other specialists to provide an accurate, understandable and up-to-date resource. The book summarises and pulls together content from the FRCR Physics Notes at Radiology Cafe and delivers it as a paperback or eBook for you to keep and read anytime. There are 7 main chapters, which are further subdivided into 60 sub-chapters so topics are easy to find. There is a comprehensive appendix and index at the back of the book.

Advances in digital technology led to the development of digital x-ray detectors that are currently in wide use for projection radiography, including Computed Radiography (CR) and Digital Radiography (DR). Digital Imaging Systems for Plain Radiography addresses the current technological methods available to medical imaging professionals to ensure the optimization of the radiological process concerning image quality and reduction of patient exposure. Based on extensive research by the authors and reference to the current literature, the book addresses how exposure parameters influence the diagnostic quality in digital systems, what the current acceptable radiation doses are for useful diagnostic images, and at what level the dose could be reduced to maintain an accurate diagnosis. The book is a valuable resource for both students learning the field and for imaging professionals to apply to their own practice while performing radiological examinations with digital systems.

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.
