This volume in the Robotic Radiosurgery series is devoted to the theory and practice in the emerging field of stereotactic radiosurgery for extracranial tumors, particularly those that move as patients breathe. Special attention is given to the frameless robotic radiosurgery device known as the CyberKnife. Moving tumors are treated with the CyberKnife using a revolutionary new tool, called the Synchrony® Respiratory Tracking System, which can track moving tumors in real time. Detailed information is provided on the technology and methodology for delivery of high doses of radiation to moving targets, radiobiological and radiological principles, and the challenges faced by clinicians performing extracranial stereotactic radiosurgery. Furthermore, there are thorough reviews of the general clinical literature on stereotactic radiation treatment of tumors of the lungs, liver, and pancreas, and the latest clinical data from clinicians conducting clinical studies using the CyberKnife.

Stereotactic radiosurgery continues to evolve in ways that allow this powerful technology to reach and treat more tumors in more patients. This volume in the Robotic Radiosurgery series is devoted to theory and practice in the emerging field of stereotactic radiosurgery (also called stereotactic body radiation therapy) for extracranial tumors, particularly those that move as patients breathe.

The book is divided into six sections. The first three sections address tumor motion due to respiration and tumor tracking techniques; dosimetry, radiobiology, and imaging; and fiducial placement systems. The fourth and fifth sections then discuss in depth the use of robotic radiosurgery to treat lung and abdominal tumors, respectively, and a final section explains emerging concepts and techniques. Within this framework, detailed information is provided on the technology and methodology for delivery of high doses of radiation to moving targets, radiobiological and radiological principles, and the challenges faced by clinicians performing extracranial stereotactic radiosurgery. Furthermore, there are thorough reviews of the general clinical literature on stereotactic radiation treatment of tumors of the lungs, liver, and pancreas, and the latest clinical data from clinicians conducting clinical studies using the CyberKnife® Robotic Radiosurgery System.

Special attention is given to the frameless robotic radiosurgery device known as the CyberKnife, the only image-guided radiosurgery system that utilizes intelligent robotics to track, detect, and correct for changes in tumor position during treatments. Tumors that move with respiration are treated with the CyberKnife using a revolutionary new tool, called the Synchrony® Respiratory Tracking System, which can track moving tumors in real-time. This and other features of the CyberKnife are detailed in chapters by CyberKnife users. In addition, researchers in the broader fieldof stereotactic body radiation therapy were invited to contribute key chapters that place the technical and clinical benefits of CyberKnife into this growing and evolving field.

Efforts have been made to achieve a homogeneous structure throughout the book, and illustrations are of a very high quality. This volume is intended for practitioners and students in all areas of oncology and medicine who are dedicated to the treatment of patients with lesions in the lungs, pancreas, and liver, lesions that move as patients breathe.
