CyberKnife VSI System
Company History Accuray's history began in 1987 when John R. Adler, M.D., professor of neurosurgery and radiation oncology at Stanford University Medical Center, developed the CyberKnife System after completing a fellowship in Sweden with Lars Leksell, MD, the founder of radiosurgery. With the CyberKnife System, Adler’s vision was to develop a non-invasive robotic radiosurgery system with superior accuracy for treatment of tumors anywhere in the body. The revolutionary concept reached far beyond the practice of radiosurgery at the time, which restricted radiosurgery to the treatment of intracranial tumors.
Cyberknife Overview The CyberKnife System is the world’s first and only radiosurgery system designed to treat tumors anywhere in the body with sub-millimeter accuracy. Using image guidance technology and computer controlled robotics, the CyberKnife System is designed to continually track, detect and correct for tumor and patient movement throughout the treatment. Because of its extreme precision, the CyberKnife System does not require invasive head or body frames to stabilize patient movement, vastly increasing the system’s flexibility.
