Comprehensive Guide to Radiographic Sciences and Technology

A Comprehensive Guide to Radiographic Sciences and Technology is a concise review of radiographic physics and imaging, perfect for students preparing for certification examinations such as the American Registry for Radiologic Technologists (ARRT). Aligned with the core radiographic science components of the current American Society of Radiologic Technologists (ASRT) curriculum, this up-to-date resource covers topics including radiation production and characteristics, imaging equipment, digital image acquisition and display, radiation protection, basic principles of computed tomography, and quality control.
 
The guide begins with an overview of the radiographic sciences and technology, followed by detailed descriptions of the major components of digital radiographic imaging systems. Subsequent sections discuss the essential aspects of diagnostic radiography and computed tomography, including basic physics, imaging modalities, digital image processing, quality control, imaging informatics, and basic concepts of radiobiology and radiation protection. Throughout the book, concise chapters summarise the critical knowledge required for effective and efficient imaging of the patient while emphasising the important, yet commonly misunderstood, relationship between radiation dose and image quality. Written by an internationally recognised expert in the field, this invaluable reference and guide:
* Provides easy access to basic physics, techniques, equipment, and safety guidelines for radiographic imaging
* Reflects the educational requirements of the American Society of Radiologic Technologists (ASRT), the Canadian Association of Medical Radiation Technologists (CAMRT), the College of Radiographers (CoR), and other radiography societies and associations worldwide
* Offers a range of pedagogical tools such as chapter outlines, key term definitions, bulleted lists, practical examples, and links to current references and additional resources
* Includes charts, diagrams, photographs, and x-ray images
 
A Comprehensive Guide to Radiographic Sciences and Technology is required reading for students in programs using ionizing radiation, those preparing for the ARRT and other global radiography certification exams, and practising technologists wanting to refresh their knowledge.
