Book Details

New high-precision technologies for the planning and delivery of radiotherapy are major advances in cancer treatment. This volume is a comprehensive guidebook to these new technologies and the many clinical treatment programs that bring them into practical use. Advances in intensity modulated radiation therapy (IMRT), 4D and adaptive treatment planning are clearly explained, and the new target localization and image-guided radiotherapy (IGRT) systems are comprehensively reviewed. Clinical tutorials fully illustrate the target definitions for the major cancer sites, and techniques for organ motion management are shown. In addition, chapters explore the technical basis for stereotactic body radiotherapy (SBRT) and the latest clinical experience with it for most organ sites. In this volume, foremost authorities explain the important new techniques and technologies of radiation oncology, and give essential treatment guidelines for its clinical and technical practitioners.

Abstract

Four-dimensional CT acquisition is commercially available, and provides important information on the shape and trajectory of the tumor and normal tissues. The primary advantage of four-dimensional imaging over light breathing helical scans is the reduction of motion artifacts during scanning that can significantly alter tumor appearance. Segmentation, image registration, visualization are new challenges associated with four-dimensional data sets because of the overwhelming increase in the number of images. Four-dimensional dose calculations, while currently laborious, provide insights into dose perturbations due to organ motion. Imaging before treatment (image guidance) improves accuracy of radiation delivery, and recording transmission images can provide a means of verifying gated delivery.
