Overview

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 641 illustrations, including meticulous color line drawings, numerous photographs and stark radiographs. Chapter 29 alone, on digital image processing, includes 40 beautifully executed illustrations. Foundational chapters on math and basic physics maintain a focus on energy physics. Obsolete and extraneous material has been eliminated, while concepts supporting digital imaging 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. No fewer than eight chapters are devoted directly to digital imaging, with the physics of digital image capture, extensive coverage of digital processing techniques, and the practical application issues of both CR and DR. Image display systems are brought up to date with the physics of LCD screens and of electronic images. In all, there are eleven full chapters dealing specifically with digital and electronic imaging concepts. Chapters on Radiation Biology and Protection include an unflinching look at current issues and radiation protection in practice. The
