This book provides a comprehensive guide to the essential materials and content needed to teach and/or learn medical physics to pass the board certification exam and make progress towards the independent practice of medical physics. It offers a concise yet comprehensive integration of the AAPM Report No. 365 curriculum with the American Board of Radiology (ABR) Part 1 Exam requirements, creating a unified resource that supports both graduate-level teaching and exam-focused learning. It synthesizes the core physics underpinning diagnostic, nuclear, and therapeutic medical physics, aligning academic preparation with the knowledge expectations of a second-year medical physics graduate. By combining curricular structure, core concepts, and clinically oriented explanations, the book provides a clear pathway for instructors and students aiming to master the content required for initial certification in medical physics. Designed for graduate students, educators, and training programs in medical physics - particularly those operating within CAMPEP-accredited environments - this book is suited to anyone preparing for or teaching the ABR Medical Physics Part 1 Exam. Whether used as a structured course companion or an independent study guide, it supports learning and exam readiness. The first in a two-volume set, this volume covers the ABR Medical Physics Part 1, General Exam Section, which focuses on medical physics at the level of common graduate courses. It also discusses ethics and professionalism. Key features:• Fully aligned with AAPM Report No. 365 and ABR Part 1 Exam content, providing a streamlined, integrated guide to core medical physics topics. • Contains nearly 900 embedded practice questions and answers. • Structured with an innovative framework which blends leading texts with updates to current professional standards and links key physics principles directly to clinical practice through diagrams, concept maps, and real-world insights.
