Expanding Radiosurgery with New Innovations

Radiosurgery noninvasively delivers high doses of accurately targeted radiation to achieve a surgically precise outcome. It has been used for decades as an effective means of destroying tumors and other lesions without the need for open surgery. The benefits of radiosurgery, however, have been limited primarily to the brain because of the need to attach a metal frame directly to the patient's skull. This unwieldy frame is required to target radiation accurately to the tumor but prevents the use of radiosurgery outside the head.

The CyberKnife represents an entirely new approach to radiosurgery. It is the only system that combines robotics and advanced image guidance to deliver true frameless radiosurgery. Multiple beams of image-guided radiation are delivered by a robot-mounted linear accelerator. The beams converge on the tumor, destroying it while minimizing exposure to surrounding healthy tissue. Elimination of the frame through the use of image-guided robotics enables the CyberKnife to treat targets located throughout the body, not just in the head. Radiosurgery can now be used in areas—such as the spine, lung, liver, pancreas, and kidney—that traditionally were difficult, if not impossible, to treat with radiosurgery, and for pediatric patients such as infants, whose skulls are too thin and fragile to undergo frame-based treatment.

Noninvasive Tumor Ablation Anywhere in the Body

The CyberKnife is an FDA-approved, noninvasive surgical tool capable of tumor ablation anywhere in the body when radiation is indicated. The image-guidance system tracks bony landmarks of the skull to target radiation accurately to lesions in the head. For treatment of lesions in the body, the image guidance tracks small markers, called fiducials, that have been implanted in the tumor to target the radiation. CyberKnife radiosurgery offers the following advantages:

  • Frameless treatment for increased patient comfort and expanded applications
  • Typically outpatient and painless option without the risk of complications associated with open surgery
  • Only system that checks and compensates for patient movement through an image-guidance system during treatment, for superior accuracy
  • Single-fraction or hypofractionated radiosurgery (usually 2 to 5 fractions) for treatment near sensitive structures
  • Greatest flexibility in approach through a computer-controlled robotic arm to access lesions in hard-to-reach locations
  • Option of isocentric (ideal for spherical lesions) or nonisocentric (ideal for irregularly shaped targets) treatment
