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.

Practical emphasis on key information needed in radiography practice makes theoretical information easy to understand and apply. Appendixes of Practical Tips, Important Relationships, and Mathematical Applications compile these features found throughout the text and organize them by chapter with page references for quick reference and study. Digital radiography coverage is integrated throughout the text, in addition to a separate chapter devoted to digital imaging (Chapter 12) that demonstrates how to acquire, process, and display digital images. Extensive coverage of film processing ensures that readers gain the knowledge and problem-solving skills they need. The chapter on Radiographic Image Formation (Chapter 3) includes new coverage of basic fluoroscopy. The chapter on radiographic image quality has been divided into two chapters: Photographic Properties of Image Quality (Chapter 3) and Geometric Properties of Image Quality (Chapter 4). The chapter on Image Receptors (Chapter 6) includes new digital information. More on quality control procedures and brief section on digital image processing have been added to the chapter on Radiographic Processing (Chapter 8). A new section of digital radiography and AEC is included in the chapter on Automatic Exposure Control (Chapter 11). A revised chapter on Digital Radiography (Chapter 12) includes the latest information on newer technologies such as direct capture imaging and more on digital image management. Practical Tips help readers understand how to apply concepts in their clinical practice. Important Relationships emphasize the important, fundamental relationships between concepts being discussed, calling attention to the fundamentals of radiographic imaging and exposure. Mathematical Applications familiarize students with mathematical formulas and show how mathematical concepts and formulas are applied in the clinical setting. Unique Film Critique Interpretations collected in an appendix include radiographic films and sets of questions that teach how to evaluate the quality of radiographic film and how to determine which factors produced a poor image.
This comprehensive guide shows how to reduce the need for repeat radiographs. It teaches how to carefully evaluate an image, how to identify the improper positioning or technique that caused a poor image, and how to correct the problem. This text equips radiographers with the critical thinking skills needed to anticipate and adjust for positioning and technique challenges before a radiograph is taken, so they can produce the best possible diagnostic quality radiographs. Provides a complete guide to evaluating radiographs and troubleshooting positioning and technique errors, increasing the likelihood of getting a good image on the first try. Offers step-by-step descriptions of all evaluation criteria for every projection along with explanations of how to reposition or adjust technique to produce an acceptable image. Familiarizes technologists with what can go wrong, so they can avoid retakes and reduce radiation exposure for patients and themselves. Provides numerous critique images for evaluation, so that readers can study poor images and understand what factors contributed to their production and what adjustments need to be made. Combines coverage of both positioning and technique errors, as these are likely to occur together in the clinical environment.
