How Does it Work?

CyberKnife® is an advanced technology that delivers a specialized form of radiation therapy called stereotactic radiosurgery, or stereotactic body radiation therapy. It is comprised of a compact linear accelerator, a machine that generates a radiation beam, attached to a highly maneuverable robotic arm.

The CyberKnife features a device that controls the width of the radiation beams the machine delivers during treatment, allowing our clinical experts to vary the beam size and treat a larger variety of tumors throughout the body.

During CyberKnife procedures, patients will lie on a treatment table while the machine’s robotic arm moves around their body delivering high doses of radiation directly to their tumor with pinpoint precision. The cumulative dose of radiation delivered by the CyberKnife kills tumor cells while minimizing exposure to surrounding healthy tissue.

Most treatment sessions typically last 30 – 90 minutes depending on the size, shape and location of your tumor.

Other features of CyberKnife:

  • Moves with virtually unlimited mobility, allowing it to deliver radiation with sub-millimeter accuracy to precise locations in a patient’s body without ever touching them
  • Utilizes an advanced imaging and tracking system that continually updates the tumor location throughout treatment procedures, compensating for patient movement and ensuring the radiation beams are locked on the tumor during treatment.
