CyberKnife Robotic Radiosurgery System The CyberKnife uses a miniature linear accelerator (LINAC) mounted on a robotic arm to deliver concentrated beams of radiation to the targeted tumor from multiple positions and angles. Thus, the tumor receives a cumulative dose of radiation high enough to control or kill the tumor cells while minimizing radiation exposure to surrounding healthy tissue.

The CyberKnife is the only system available which can also compensate for patient movement to ensure highly accurate delivery of radiation during treatment.

The patient lies on a table and wears a custom-fit mesh facemask while the robotic arm delivers the radiation. Most treatments typically last about an hour per lesion, after which the patient can get up and go home the same day. Patients being treated for extracranial tumors or lesions may need to undergo placement of fiducials, or "markers" near the tumor, prior to treatment.

Clinical benefits:

• Delivers treatment with sub-millimeter accuracy
• Treats extracranial and intracranial lesions
• Enables treatment of lesions previously determined too difficult to treat
• Ablates tumors while minimizing radiation to healthy tissue and critical structures
• Delivers high cancer killing doses with minimal or no side effects
• Eliminates the need for head or body frame
• Provides an alternative to surgery that is convenient and non-invasive

Technical advantages:

• Utilizes the world's only intelligent robotic technology designed for radiosurgery
• Automatically and continuoisly tracks, detects, and corrects for lesion and patient movement
• Fully integrated robotic system allows unprecedented treatment faxibility
• Patient-centric design enables relaxed treatement experience
• Extensively proven, proprietary, patented technology
  • Over 16,000 patients treated
  • Over 140 treatment facilities
  • Over 130 medical papers published
