Designed to help the x-ray technologist prepare for the Physics component of the American Registry of Radiologic Technologists (ARRT) examination. This book only addresses 60% of the AART examination that is directly related to Physics, the material that gives most students the greatest difficulty. Key aspects of RT X-Ray Physics Review are: Comprehensive Content: Identifies the important Physics facts that all students need to know to pass the Radiation Protection, Equipment Operation & Quality Control, Image Production & Evaluation sections component of the AART examination. Organization: Presents the material in 15 chapters subdivided into four or five major topics to facilitate reading and understanding, with explanatory tables and figures in each topic. Questions: Includes 450 questions, 30 pertaining to each of 15 chapters, and two comprehensive tests of 100 questions each at the end of the book. Answers provided. Appendixes: Useful tables of radiologic quantities and units. Comprehensive Radiological Physics bibliography.
