Christensen's physics of diagnostic radiology. 4th edition

This book presents a complete outline of the basic physics of diagnostic radiology, with minimal reliance on advanced math and physics. The fourth edition retains most of the previous edition's basic information regarding the production and detection of x-rays and interactions between x-rays and tissues. Otherwise changes in the text are plentiful. The chapter on x-ray generators contains new material on semiconductors, diodes, new generators, high capacity x-ray tubes, intensifying screen phosphors, and film and film processing. Viewing and recording of the fluoroscopic image are discussed in two rewritten chapters, reflecting changes in fluoroscopic generation, display, and recording. New coverage of Xeroradiography includes the latest information on the Xerox higher sensitivity system. Changes in computed tomography are detailed, and new equipment surveyed. Three-dimensional image construction is introduced, and expanded discussion of pulsed Doppler ultrasound and color Doppler flow imaging is included. Nuclear magnetic resonance (NMR) is detailed in an expanded chapter. An additional new chapter discusses the use of MRI.
