This book provides comprehensive and cohesive instruction in the technology and evaluation of radiographic and fluoroscopic imaging, particularly those incorporating digital image receptors. The tools needed for specifying, inspecting, and evaluating these systems are used as a unifying frame-work for reviewing the state-of-the-art of radiographic and fluoroscopic systems, the principles of image quality analysis, the technology and digital receptors, and techniques available to evaluate - and maintain - the clinical performance of these systems. Emphasis is on clinical practicality, clinical applicability, and consistency, with guidelines and recommendations from various sources.
