Proton Therapy System Supplied by American Shared Hospital Services Begins Treating Patients at UF Health Cancer Center-Orlando Health in Florida

San Francisco, CA – April 7, 2016 -- AMERICAN SHARED HOSPITAL SERVICES (NYSE MKT:AMS),a leading provider of turnkey technology solutions for advanced radiosurgical and radiation therapy services, announced today that physicians have begun treating patients with the MEVION S250 proton therapy system AMS supplied to The Marjorie and Leonard Williams Center for Proton Therapy at UF Health Cancer Center-Orlando Health in Florida.   

AMS Chairman and Chief Executive Officer Ernest A. Bates, M.D., said, "This first proton treatment at The Marjorie and Leonard Williams Center for Proton Therapy at UF Health Cancer Center-Orlando Health is the culmination of years of hard work and dedication by all of us at AMS to make our first proton center a reality.  We congratulate the proton therapy team at UF Health Cancer Center-Orlando Health on achieving this milestone. 

"Proton therapy is an external-beam radiation therapy technique similar to conventional high energy X-rays. The difference is that protons are heavy charged particles that deposit radiation in a targeted manner--when they reach a specific depth, protons deposit their energy and then stop, leaving virtually no energy beyond that depth.  The depth is precisely controlled by changing the energy of the protons, thus allowing physicians to precisely tailor the proton dose to the specific depth and shape of the tumor, and thereby greatly reducing the dose to surrounding healthy tissue.  Only 21 proton centers are in operation in the U.S. today.  But with the increasing awareness among physicians and patients of proton therapy's advantages in the treatment of certain cancers, we at AMS look forward to developing many additional proton centers at hospitals around the country in the years to come."

The Marjorie and Leonard Williams Center for Proton Therapy is housed in a new, 15,000 square foot facility consisting of three floors--two above ground and one underground--to accommodate the MEVION S250 superconducting synchrocyclotron proton accelerator.
