   978-0323566681Prepare for success on the ARRT examination and in the practice of radiography! Basic principles of X-ray Physics and Imaging, 3^rd Ed. adheres to the ASRT recommended curriculum and focuses on what the radiographer requires to understand to safely and proficiently conduct radiographic examinations. This comprehensive text provides you a foundational comprehension of fundamental physics concepts such as atom structure, electricity and magnetism, and electromagnetic radiation. It then encompasses imaging principles, radiation production and characteristics, digital image quality, imaging equipment, digital image acquisition and display, image analysis, and more- linking physics to the daily practice of radiographers. New for the third edition is updated information on radiation classifications, a shift in focus to SI units, and a fully updated chapter on Fluoroscopic Imaging.

   • UPDATED! Material reflects the latest standards defined by the ARRT and ASRT, giving you the information you needed to pass the boards.
   • Chapter Overview Questions at the end of each chapter enable you to assess how effectively you have mastered the material in each chapter.
   • Critical Thinking Questions at the end of each chapter provide opportunity for evaluation and greater challenge.
   • Key Concept boxes further explain and emphasize key points in the chapters.
   • Radiation Safety callout boxes help you understand the ethical responsibilities to minimize radiation dosages, shielding, time and distance, how to limit the field of exposure and what that does to minimize dose, and technical factors and how they affect the primary beam and image quality.
   • Over 400 images and line drawings encourage you to visualize important concepts.
   • Effective pedagogy, including chapter objectives, key terms, outlines, bulleted chapter summaries, and specialty boxes, help you organize information and focus on what’s most important in each chapter.
   • An emphasis on the practical information highlights just what you need to know to ace the ARRT examination and become a competent practitioner.
   • Numerous critique exercises teach you how to evaluate the quality of radiographic images and determine which factors produce poor images.

   • NEW! A shift in focus to SI units aligns with international system of measurement.
   • UPDATED Information regarding radiation classifications allows you to understand radiation levels.
   • NEW! Inclusion of advances in digital imaging helps familiarize you with state-of-the-art pictures.
   • NEW and UPDATED! Expanded Digital Fluoroscopy section, familiarizes you with the equipment you’ll encounter.
