February 16, 2009 - Varian Medical Systems will supply proton therapy equipment for the planned three-room treatment facility, which American Shared Hospital Services (AMS) is developing in the San Francisco Bay area.
AMS has entered into a non-binding agreement with Varian to supply proton therapy equipment, and AMS currently is evaluating several potential sites, and is forming a consortium of hospital partners for what should be the first PBRT center in Northern California.
“Subject to financing and FDA clearance, we and our partners hope to begin treating patients at our PBRT facility in San Francisco by 2011,” said Ernest A. Bates, M.D., chairman and CEO of American Shared Hospital Services.
AMS has previously announced contracts to place PBRT devices at Tufts Medical Center in Boston, Orlando Regional Healthcare (with professional services to be provided exclusively by M.D. Anderson Cancer Center Orlando), and Long Beach Memorial Medical Center (in partnership with A.M. Nisar Syed & Associates, a leading radiation oncology group). "We are negotiating contracts to place additional PBRT systems in medical centers throughout the country," Dr. Bates said.
