Summary:
"This book is a concise, one-stop resource on medical imaging written for medical professionals, addressing a field of critical importance to them, in the language that they speak. Coauthored by a medical physicist and a clinical imaging physician, the book provides a solid working knowledge of the science and technology of image formation, including coverage of imaging modalities and how they operate, how to use the resulting diagnostic information, the proper applications of imaging, and many clinical case examples." -- Publisher.
