Request a sales quotePrepare for success on the ARRT exam and in clinical practice! Essentials of Radiographic Physics and Imaging, 4th Edition, follows the ASRT recommended curriculum and focuses on what you need to understand to safely and competently produce high-quality radiographic images. This comprehensive text gives you 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.
- 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 you prepare for certification exams.
- UPDATED! ARRT guidelines are reflected throughout, including the most up-to-date shielding guidelines.
- End-of-chapter review questions allow you to strengthen and assess your understanding of key concepts.
- End-of-chapter Questions to Ponder challenge you to apply your 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 you 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 visually reinforce important concepts.
- Strong pedagogy, including chapter objectives, key terms, outlines, and summaries, helps you organize information and ensure that you understand what is most important in every chapter.
- Practical approach emphasizes the information you need most for course, ARRT exam, and career success.
- Numerous critique exercises teach you how to evaluate the quality of radiographic images and determine which factors produce poor images.
