Seattle CyberKnife Center

Interactive robotics. Advanced target guidance.
Real-time motion tracking.

CyberKnife is the only stereotactic radiosurgery system that uses a compact linear accelerator (linac) mounted on a computer-controlled robotic arm. Image guidance technology is then used to accurately target and track the position of the tumor in real time. The result is destruction of the tumor with minimal damage to surrounding tissues.

Live images of the tumor are taken during patient setup and throughout the treatment process. Image guidance cameras [ 1 ] are used to locate and track the position of the tumor throughout the treatment. Mounted on a robotic arm [ 2 ] , a linear accelerator [ 3 ] is used to deliver multiple beams of radiation at optimal angles to the tumor site while continuously adjusting for the patient's respiratory motion and movement.

Robotic flexibility and dynamic motion tracking allow the CyberKnife System to treat a variety of tumors and conditions that cannot be treated with traditional radiation therapy or conventional surgery.
