How Does CyberKnife Work?
CyberKnife is a non-surgical procedure that delivers high doses of radiation to cancerous and benign tumors without damaging nearby healthy tissue and organs. Utilizing precision technology developed to guide cruise missiles to their target, CyberKnife represents a significant advancement in stereotactic radiosurgery.
4 Year Follow-up
During the CyberKnife procedure, more than 100 beams of radiation produced by a linear accelerator enter the body from different angles. By itself, each small beam of radiation does not harm the healthy tissue or organs it passes through. It is when each of these beams intersects at the target that a high enough dose is delivered to destroy the tumor and stop the progression of abnormal cell growth.
CyberKnife's advanced image-guided stereotactic robotic system delivers radiation so precisely that it can stay on target even if a patient moves during treatment. With its attached linear accelerator, CyberKnife's robotic arm delivers radiation to a specific target, guided by a computerized 3-D map created through the use of CT or MRI scans. Any movement by the patient is compensated for by the robotic system, ensuring optimal accuracy throughout treatment.
