This book presents a comprehensive introduction to the principles and techniques of radiographic imaging. The physics principles that are the foundation of radiography are explained clearly, with numerous illustrations, examples and solved problems to aid comprehension. Chapters are organized into six units: Creating the Beam, Protecting Patients and Personnel, Creating the Image, Analyzing the Image, Comparing Exposure Systems, and Special Imaging Systems. Specialized imaging modalities, such as mammography, magnetic resonance imaging, and computed tomography and computed radiography, are explained in individual chapters.
