The How Radiology Works physics review as a book. ARRT-aligned x-ray physics, digital imaging, and radiation protection — $2.99 on Kindle, paperback if you want it on the desk.
Hundreds of color illustrations.
How Radiology Works has always been bite-size videos and articles on x-ray and CT physics. Radiography Physics Mastery is that teaching in one place, written to the ARRT Radiography Content Specifications.
It is for students who get positioning in lab and still freeze on the tube, the detector, and the math. It is not a positioning book. It does not replace your program or a full-registry Qbank. It is the physics companion.
500 pages in paperback. Same author you already watch: Brian Nett, PhD.

What readers say
From Amazon (Kindle and paperback).
Radiography Physics by Brian Nett is an exceptional cornerstone text for students and practitioners alike in medical imaging. Dr. Nett masterfully balances depth with clarity, presenting complex physical principles in a way that is both accessible to learners and sufficiently rigorous for advanced study. The book bridges the often-daunting gap between theoretical physics and its practical application in everyday radiographic practice, making it an invaluable resource for radiography students, educators, and clinical professionals.

A great resource to understand medical physics. The CT concepts I am familiar with were well described and excellently presented. I wish it had been available a few decades ago. The author covered other modalities in a very understandable way. This demonstrates a great range, something for those experienced and accessible for the newcomer to the field.

Studying radiography physics can be really intimidating — it pulls together math, physics, electronics, and image processing, all at once. What I liked most about this book is how it turns the learning process into a story with two heroes and “missions.” Instead of feeling like I was grinding through formulas, it felt more like progressing through challenges, which honestly made studying a lot more fun and less stressful.
— Henry, Amazon review
Radiography Physics Mastery is one of the most effective and approachable study resources I’ve come across for anyone preparing for the ARRT exam or looking to strengthen their understanding of imaging fundamentals. The author breaks down complex physics, digital imaging concepts, and radiation protection principles in a way that feels clear, logical, and genuinely helpful. The explanations are concise without sacrificing depth, and the structure makes it easy to build confidence as you go.
