Image Guidance in Radiation Therapy: Techniques, Accuracy, and Limitations (Monograph)

American Association of Physicists in Medicine (AAPM), 2018 8vo (23.5 cm), 406 pp. Publisher's laminated boards. "Image-guided radiation therapy (IGRT) has been used since the inception of radiation treatment, but its usage became routine with the development of gantry-mounted cone-beam CT systems in the early 21st century. IGRT is now the norm in the clinics equipped with modern radiation therapy delivery systems. All patients undergoing radiation therapy benefit from this widely available technology, as it enables more accurate delivery of radiation to the intended targets. The 2018 summer school and this book cover all the important aspects of current IGRT techniques used in clinics, as well as some emerging technologies that may become available in the future. Since IGRT is a confluence of radiation therapy and imaging physics, many of the topics covered here focus on the application of imaging physics in therapy. Although the majority of image-guidance devices use ionizing radiation, the imaging modalities that use non-ionizing radiation are also included here. This book provides an overview of the state-of-the-art image-guidance techniques employed in radiotherapy, and it provides necessary information to medical physicists who would like to know about current image guidance techniques and modalities."
