An introductory chapter reviews basic principles of treatment planning, including field arrangements, type and energy of radiation, shielding, and beam modification. The sections which follow consider tumors at specific sites. Each section contains a brief overview of the role of radiation therapy, the pertinent regional anatomy, methods of assessing the extent of tumor, and how to define treatment volume. There are practical instructions for patient positioning, choice of field arrangements, and implementation of the final plan. Separate chapters on pediatric tumors and systemic and palliative radiation complete the work. The text is supplemented by anatomic drawings and radiographs.
