Khan lectures became my Bible of Radiation Oncology , an Older version I could read this textbook on my own during the multiple racism attacks I was facing in Radiation Oncology. I was not allowed in lecture theatres and lectures by my racist professor and colleagues, I started reading this book as it was a free copy on google, before the new colorful Khan This has no colors and has less new technology on Radiation Treatment, a good read for lectures if you can't afford or dont want to spend money or want to just browse to get a feel, it's now too outdated but good keeps
The fourth edition of this book is more colorful and the pages are smoother but the material is almost the same as the previous edition [3rd edition]. The book is easy to read for students and a quick reference for medical physicists. the book takes the reader gradually from the basics to the point where the core of medical physicist work rely. The background mentioned in the first few chapters is clear and brief.
A prescribed text, this book was incredibly expensive and, having previously studied physics as a minor, I could have completed my coursework without having to spend $250 on this textbook. Probably best to save your pennies and borrow it from the library.
