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.
