Cyberknife VSI system (Accuray) used in Stereotactic Radiosurgery

The Cyberknife VSI system, from Accuray Inc., has been utilised in a new treatment method, stereotactic body radiotherapy (SBRT), which offers a more effective way to treat gynecologic cancers, shortening radiation treatment time from five weeks to three days. Unlike traditional radiation therapy, SBRT uses focused radiation beams and targets well-defined tumors. In order to focus in on the region, the tumors need to be imaged and marked (using fiduciary markers) in advance. During treatment with the Cyberknife system patients need to be immobilized, and even the movement from the patient's breathing needs to be taken into account. The method will be published in the Journal of Visualized Experiments (JoVE) on April 17. See: "Stereotactic Radiosurgery for Gynecologic Cancer" by Charles Kunos et al. JoVE 3793 4/17/2012
