From the reviews of the fifth edition:“This book Provides a unique approach to covering the physics of radiation oncology. … I would highly recommend this book for radiation oncology trainees who are seeking to understand the physics background to clinical radiation oncology treatments and for physics trainees who are seeking to understand how basic physics applies to clinical application. I would also recommend this book for any radiation oncology professional looking to update their knowledge on either a particular radiotherapy technique or clinical treatment site.” (Lois Holloway, Australasian Physical & Engineering Sciences in Medicine, Vol. 36, 2013)
