Prepare your students for success on the ARRT exam and in clinical practice! Essentials of Radiographic Physics and Imaging, 4^th Edition, follows the ASRT recommended curriculum and focuses on what the radiographer needs to understand to safely and competently produce high-quality radiographic images. This comprehensive text gives students a foundational understanding of basic physics principles such as atomic structure, electricity and magnetism, and electromagnetic radiation. It then covers 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 to this edition is updated information on radiation classifications, a shift in focus to SI units, and coverage of the latest advances in digital imaging.

Key Features
- UPDATED! Content features a shifted focus to SI units, current information on radiation and classifications, and coverage of the latest advances in digital imaging
- UPDATED! The newest ARRT and ASRT standards are incorporated throughout to help prepare students for certification exams
- UPDATED! ARRT guidelines are reflected throughout, including the most up-to-date shielding guidelines
- End-of-chapter review questions provide opportunities for students to strengthen and assess their understanding of key concepts
- End-of-chapter Questions to Ponder challenge students to apply their knowledge and critical thinking skills
- Points to Remember box in each chapter helps highlight the most critical aspects of the material presented
- Coverage of radiation protection in callout boxes helps students understand the core principles of ethical obligations 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 represent the quantity and quality of radiation
- More than 400 line drawings encourage students to visualize important concepts
- Strong pedagogy, including chapter objectives, key terms, outlines, and summaries, helps students organize information and ensure that they understand what is most important in every chapter
- Practical approach emphasizes the information most needed by students for course, ARRT exam, and career success
- Numerous critique exercises teach students how to evaluate the quality of radiographic images and determine which factors produce poor images
