International Journal of Radiation Oncology, Biology, and Physics, Volume 68, Issue 1 -- "An update to this text is welcomed. New chapters in this edition include well-written discussions of image-guided radiotherapy, patient and organ movement, and high-dose rate brachytherapy. Many chapters have undergone extensive revisions. The clinical chapters are all well organized, and the figures are generally pertinent and well presented. Overall the book provides a well-organized view of the current state of the art in radiotherapy planning. The updated information greatly improves the relevance of the technical chapters of this book over the earlier edition. This new edition should become a popular and useful reference for clinical physicist and radiation oncologists."
