CyberKnife is the world's most accurate radiosurgery instrument for treating tumors and lesions that were once considered inoperable. Saint Peter's University Hospital is one of a select group of medical institutions in the country currently offering the breakthrough CyberKnife treatment.

CyberKnife is a robotic stereotactic radiosurgery system that non-invasively treats inoperable or complex tumors. It delivers beams of high-dose radiation with pinpoint accuracy in a manner that does not cause any patient discomfort, nor does it require minimizing patient movement, as do other methods do.
