Stereotactic radiosurgery (SRS) is a highly specialized type of external beam radiation treatment in which a precise and conformal, image-guided focus of ionizing radiation is delivered to a well-defined target volume in a single procedure. The origins of radiosurgery date back to the 1960s and the use of cobalt based techniques. Over the past 10–15 years, linear accelerators have been designed to allow for the delivery of radiosurgery as well. Robotic radiosurgery couples a linear accelerator to a robotic articulated manipulator which allows for the delivery of both SRS and fractionated SRS (also referred to as stereotactic body radiation therapy (SBRT)). In addition, since frameless techniques are most often employed with robotic radiosurgery, areas outside the cranium can now be treated with similar accuracy. Robotic radiosurgery is currently being used to treat targets located in the brain, spine, head and neck, lung, liver, pancreas, prostate amongst others. This chapter provides the background and technical details of robotic radiosurgery, as well as the current evidence for treatment of various body sites.
