How Cyberknife Works

Cyberknife uses image guided technology and computer controlled robotics to deliver high doses of radiation to the tumor with submillimeter accuracy. This is a non-invasive treatment that eliminates the metal head frame used in other stereotactic radiosurgery. The patient lies on the treatment table while the robotic arm moves around him or her. X-ray images are taken throughout the treatment, and the RoboCouch™ is adjusted according to tumor or patient movement. The couch can be adjusted in the room or the planning station.




Accuray's RoboCouch™ System allows patient positioning in six degrees of freedom:



  1. Anterior/Posterior
  2. Superior/Inferior

  3. Left/Right

  4. Roll

  5. Pitch

  6. Yaw
