Book Description
Industrial radiography is a well-established non-destructive testing (NDT) method in which the basic principles were established many years ago. However, during 1993-95 the European Standards Organisa tion (CEN) commenced drafting many new standards on NDT including radiographic methods, and when completed these will replace national standards in all the EC member countries. In some cases these standards vary significantly from those in use in the UK at present. These CEN standards are accepted by majority, not unanimous voting, so they will become mandatory even in countries which vote against them. As most are likely to be legal by the time this second edition is published, they are described in the appropriate places in the text. The most important new technical development is the greater use of computers in radiology. In the first edition, computerized tomography was only briefly mentioned at the end of Chapter 11, as it was then largely a medical method with only a few equipments having found a place in industrial use. The method depends on a complex computer program and a large data store. Industrial equipments are now being built, although their spread into industry has been slow. Computer data storage is also being used for radiographic data. Small computers can now store all the data produced by scanning a radiographic film with a small light-spot, and various programs can be applied to these data.

Book Description
This book provides radiological technicians, radiologists, technicians, developers and sales engineers with a unique display of the methods and applications used in radiography. Building on the physical basis and the quality and effects of X-rays, the book describes X-ray systems for diagnostics and interventions, the technique behind a radiographic image, image quality, patient data management including data archiving and communication with PACS in the hospital as well as between a physician's practice and hospitals. All descriptions are in accordance with the technical and diagnostic requirements to be met by modern, frequently digital radiographic as well as image processing methods and systems.

Book Description
This eighth edition is a major revision and update of Fuch 's Radiographic Exposure and Quality Control including a title change. The book is a most expansive and comprehensive text on radiographic exposure and imaging, encompassing the vast and intricate changes that have taken place in the field. As with previous editions, the book is intended to complement radiographic physics texts rather than duplicate them, and all chapters on conventional radiography have been fully revised to reflect state-of-the-art imaging technology. Part I, Producing the Radiographic Image, presents chapters on x-rays and radiographic variables, recording the permanent image, qualities of the image, and interactions of x-rays within the patient. Part II, Visibility Factors, includes chapters on milliampere-seconds, kilovoltage-peak, machine phase and rectification, beamfiltration, field size limitation, patient status and contrast agents, pathology and casts, scattered radiation and image fog, grids, intensifying screens, and image receptor systems. Part III, Geometrical factors, discusses focal spot size, the anode bevel, source-image receptor distance, object-image receptor distance, distance ratios, beam-part-film-alignment, geometric functions of positioning, and motion. Part IV, Comprehensive Technique, presents chapters on analyzing the radiographic image, simplifying and standardizing technique, technique by proportional anatomy, technique charts, exposure controls, patient dose, quality control, and solving multiple technique problems. Part V, Special Imaging Methods, includes a concise overview of computers, the nature of digital images and the fundamental processes common to all digital imaging systems. Specific applications follow, including digital conversion of film images, DR, DF, CR, and image reconstruction in CT and MRI. The methods of Three-Dimensional Imaging are then introduced with beautiful illustration. The application of lasers in digitizing images and printing hard copies is reviewed, ending with a balanced discussion of PACS and digital teleradiology. CR and DR provides thorough coverage of the image matrix, pixel size, and fields of view, gray scale enhancement and spatial resolution, followed by an excellent discussion of CRT image qualities including horizontal and vertical resolution, contrast, dynamic range, and signal-to-noise ratio. Exposure and reading of the photostimulable phosphor plate is nicely illustrated. Clear presentations on windowing concepts, smoothing, edge enhancement, equalization, the digital workstation and display station are given. Part VI, Processing the Radiograph, completes the text with chapters on digital processing applications, practical applications for CR, automatic processors, film handling and duplication procedures, and sensitometry and darkroom quality control. Each chapter concludes with an examination that will help the student review materials and put them into perspective. Multiple choice, fill-in-the-blank, and identification/explanation questions are all included. This book is by far the best available for schools that are focused on the practical application of radiographic technique.

Book Description
Computed radiography is one of the most promising digital radiography techniques, and is expected to replace the conventional screen film radiography in the near future. This book is the first textbook on computed radiography written by Japanese authors and describes basic technologies and clinical results obtained at various hospitals. There are more than 60 CR systems working in clinical environments in Japan. However, as yet there are not so many systems working outside Japan. This book is, therefore, a good introduction to the new technology and practice of the CR system all over the world.

Book Description
This book addresses radiation protection of patients having digital radiography and computed tomography (CT) examinations. The literature on radiation doses to patients from these two modalities have reported that the doses to patients are high. As a result, the radiology community has focused on methods and procedures to keep these doses as low as reasonably achievable (ALARA) without compromising the diagnostic image quality. This book outlines the motivation for dose optimization in radiology, identifies and describes the ICRP principle of optimization, outlines the factors affecting the dose in digital radiography and in CT, and identifies and describes strategies used in digital radiography and in CT for dose optimization. This book is intended for all those working in digital radiography and CT environments including radiological technologists, and radiographers, radiologists, biomedical engineering technologists, and student medical physicists. It is best used as a supplement to radiologic science textbooks, and in particular, radiation protection textbooks. Furthermore, this book lays the foundations for students and practitioners engaged in research on dose reduction and dose optimization in radiology. · Provides practical and useful methods for optimization of doses from digital radiography and CT · Describes the International Commission on Radiological Protection (ICRP) principle of optimization · Outlines the factors affecting the dose in digital radiography and in computed tomography
