System to be Installed in One of Canada's Largest Academic Cancer Centers

SUNNYVALE, Calif., June 26 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery today announced that Centre Hospitalier de l'Universite de Montreal (CHUM) has purchased a CyberKnife(R) Robotic Radiosurgery System for installation at Hopital Notre-Dame du CHUM, in Montreal, Canada.

CHUM, one of the largest radiation oncology centers in Canada, will utilize the CyberKnife System to treat both intracranial and extracranial tumors including those in the lung, spine and prostate.

CHUM is one of the leading academic sites in North America for the number of accruals for protocols developed by the Radiation Therapy Oncology Group (RTOG) of the American College of Radiology (ACR), demonstrating the center's leadership in research and innovation.

In addition to being an important purchase for the people of Canada, the addition of a CyberKnife System at CHUM provides an opportunity for continued research and clinical investigation, said Euan S. Thomson, Ph.D., president and CEO of Accuray. We are thrilled to be working with such a reputable teaching facility that's had continued success in accruing patients under protocol.

In Quebec, authorization is required from a regional authority to acquire certain medical technologies, such as imaging and radiation therapy. CHUM secured approval in May 2008 and plans to install its CyberKnife System by early 2009.
