Summary
Brief summary (as posted)
Radiosurgery is precisely delivered high dose radiation. It can be performed using multiple cobalt sources, a modified traditional gantry-based linear accelerator or a robotic linear accelerator. The treatment of brain metastases represents the most common indication for radiosurgery while new indications for this technology are continually being discovered. With the increasing importance of radiosurgery and the resource implications for radiotherapy programs the investigators have proposed the first direct technological comparison of robotic to linear accelerator radiosurgery for brain metastases.
