ReseñaThe techniques and instrumentation of medical imaging have rapidly evolved over the course of the past few years. Medical Imaging Physics, the premier resource in its field, now in its fourth edition, has been revised to include novel and emerging imaging approaches in the same clear and understandable but thorough manner of the former editions. William Hendee and Russell Ritenour's comprehensive text provides the tools necessary to be comfortable with the physical principles, technology concepts, equipment, and procedures used in diagnostic imaging, as well as to appreciate the technological capabilities and limitations of the discipline. Readers need not possess a background in physics. Broadly accessible, Medical Imaging Physics covers all aspects of image formation in modern medical imaging modalities, such as radiography, ultrasonography, computed tomography (CT), nuclear imaging, and magnetic resonance imaging. Other topics covered include: Digital x-ray imaging; Doppler ultrasound; Helical CT scanning Accumulation and analysis of nuclear data; Experimental radiobiology; Radiation protection and safety. Each chapter is composed of summaries, questions, and problems, as well as sidebars highlighting historical aspects and key facts and concepts; additionally, the Fourth Edition contains over 200 completely new figures. Physicians and residents in radiology and nuclear medicine, in addition to physicists, engineers, radiobiologists, and technologists working with diagnostic imaging technology, will find Medical Imaging Physics to be a vital addition to their professional libraries.
