Accuray Strengthens Leadership Position In Robotic Radiosurgery With Next-Generation CyberKnife Announcement

SUNNYVALE, Calif., Nov. 23 /PRNewswire/ -- Today, Accuray announced The California Cancer Center in Fresno, the first site to install the CyberKnife G4 System, has successfully performed 25 treatments in the system’s first month of operation at the Center. Taking advantage of next generation CyberKnife’s ability to treat extracranial as well as intracranial tumors, the California Cancer Center has used the CyberKnife to treat patients with lung, spine and brain lesions.

“We are fortunate to be the first site to work with this new platform, and the system’s performance during our first 25 treatments has been impressive,” says Dr. Douglas S. Wong, Medical Director of Radiation Oncology at the California Cancer Center. “It is fitting that our initial CyberKnife treatments have benefited patients with spine and lung lesions that could not have been treated with our previous frame-based system.”

With the percentage of treatments for extracranial indications in the United States surpassing 50% during the three month period ending September 30, 2005, access to this advanced technology is more critical than ever before. CyberKnife is meeting this demand with more than 122 systems installed or under contract to be installed at customer sites worldwide. At the heart of this widespread acceptance is the CyberKnife’s demonstrated ability to complement a physician’s practice by generating new referrals for treatment.

“We are extremely excited about the positive reception this next-generation platform has generated from our customers,” says Eric Lindquist, Chief Marketing Officer at Accuray. “The ability to treat tumors throughout the body with sub-millimeter accuracy establishes CyberKnife as the leader in robotic radiosurgery.”

An estimated 1,000 attendees witnessed the unveiling of the new CyberKnife G4 platform on the ASTRO exhibit floor. This tremendous interest was also reflected in the significant rise in daily lead generation, which increased by 85% over the previous year.

About the CyberKnife System

The CyberKnife Robotic Radiosurgery System is the world’s only radiosurgery system that utilizes intelligent robotics. This enables the CyberKnife to ablate tumors anywhere in the body with sub-millimeter accuracy. The CyberKnife System 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 combination of image guidance and computer controlled robotics to continuously track, detect and correct for tumor and patient movements throughout the treatment with pinpoint accuracy. Because of the extreme precision and accuracy of the CyberKnife, no head or body frame is required. CyberKnife has proven to attract a new patient population to a physician’s practice and complements existing radiation therapy, IMRT or IGRT programs. With over 120 systems sold and a large body of peer-reviewed publications supporting its clinical practice, the CyberKnife has treated over 16,000 patients worldwide.
