The Physics of Radiotherapy X-Rays from Linear Accelerators

This book describes physical properties of x-ray beams produced by medical linear accelerators. It deals with mathematical modeling and dosimetry of radiotherapy x-ray beams. It also includes traditional modeling methods as well as convolution and Monte Carlo methods. Ionization chamber and TLD dosimetry are dealt with in detail and new dosimetry techniques such as radiochromatic film are also discussed. This book links dose to radiobiological effect and tumor control probability by use of the linear quadratic model. The book is designed as a comprehensive reference for medical radiation oncology physicists as well as a reference text and tutorial for students. Dosimetrists, radiation therapists, and oncologists who have a particular interest in radiation dose distributions in patients will also find the book useful, especially in regard to dose distributions in and around inhomogeneities.
