Next-generation surgical robot for therapeutic radiology unveiled

13 November 2005

Sunnyvale, California, USA.  Accuray has launched the latest generation of its intelligent robotic radiosurgery system, CyberKnife. It combines  image-guidance technology and computer-controlled robotics to deliver sub-millimetre radiosurgery.

The new system was unveiled at the 47th annual meeting of the American Society of Therapeutic Radiology and Oncology (ASTRO) in October.

CyberKnife is the world’s first and only intelligent robotic radiosurgery system, enabling delivery of sub-millimeter clinical accuracy to lesions throughout the body. This combination of image-guidance technology and computer-controlled robotics gives physicians the ability to continuously track, detect, and correct for tumor and patient movements throughout the treatment. The new CyberKnife platform builds has a new 600 MU/min linear accelerator that delivers a 50% higher dose rate than the previous generation, significantly reducing treatment times. It also features flush-mounted, in-floor X-ray detectors, providing a significant increase in treatment workspace and further expanding the potential for extracranial applications.

“We have been fortunate to be among the first to witness and adopt this new technology, and it is truly remarkable,” says Dr. Douglas S. Wong, Medical Director of Radiation Oncology at Fresno Community Cancer Center. “We have been familiar with CyberKnife technology for years, and it’s a solid, impressive platform to build on. We have treated our first patients with this system and the performance is excellent. It brings exceptional value to our oncology practice.”

“This new generation of CyberKnife is a dramatic advance in the field of radiosurgery. CyberKnife continues to be the first and only system designed for dedicated radiosurgery. The design was influenced by feedback from our customers who requested a system that could deliver sub-millimeter accuracy for tumors anywhere in the body,” said Euan Thomson, Ph.D., President and CEO of Accuray Incorporated. “The result is a complete, intelligent robotic system that constantly images, analyzes, tracks, and corrects based on critical patient information to enable a higher level of care.”

About the CyberKnife System

The CyberKnife Robotic Radiosurgery System was developed in cooperation with Stanford University. Its intelligent robotics enables it to ablate tumors anywhere in the body with sub-millimeter accuracy. It treats patients in single or staged (typically 2-5) sessions by delivering multiple beams of precisely directed radiation that converge upon the tumor while minimizing injury to surrounding healthy tissue. The CyberKnife uses a fully integrated robotic system that includes real-time image guidance to deliver radiation with pinpoint sub-millimeter accuracy while it precisely monitors and corrects for patient and tumor movement. Because of the extreme precision and accuracy of the CyberKnife, no head or body frame is required.
