"… this book arrives at an opportune time for the student of and the expert in this form of radiation treatment. … a worthwhile and informative addition to this increasingly important branch of radiotherapy."—Journal of Radiotherapy in Practice, 2015"In this text, the editors and authors have taken on a new strategy in their approach to covering the topic of stereotactic radiosurgery and stereotactic body radiotherapy … this book explores the historical developments of the Gamma Knife and linac-based SRS, the physics and radiobiology of SRS and SRT using photons and charged particles, dedicated SRS and SBRT devices, patient positioning and immobilization strategies, as well as a comprehensive clinical chapter on the various disease sites with relevant ongoing and completed protocols. This refreshing approach for assessing SRS and SBRT thereby allows the reader to explore well-referenced chapters on many individual aspects of the developing field. We trust the physicians, physicists, and other professionals involved in radiation oncology will find this book very valuable for their practice of SRS and SBRT."—From the Foreword by James Larner, MD, and Jason Sheehan, MD, PhD, University of Virginia
