SAN FRANCISCO--([ BUSINESS WIRE ])--AMERICAN SHARED HOSPITAL SERVICES (AMEX:AMS), a leading provider of turnkey technology solutions for advanced radiosurgical and radiation therapy services, announced today that it has entered into a contract to supply a Leksell Gamma Knife® Perfexion^TM system to Kettering Medical Center, Kettering Ohio. This new Perfexion system, the sixth placed by AMS to date, will replace an existing Gamma Knife supplied by AMS and is expected to begin treating patients in the first half of 2009.

"Kettering Medical Center is renowned for bringing the latest medical technology to patients in southwest Ohio. We are especially pleased to be one of the first cancer centers in the United States to offer the Leksell Gamma Knife Perfexion system, which refines and expands the therapeutic potential for radiosurgery procedures in the brain, skull, cervical spine and head & neck regions and is widely regarded as the most advanced stereotactic radiosurgery system available today," said Walter Sackett, Vice President of Clinical Services for Kettering Medical Center.

AMS Chairman and Chief Executive Officer Ernest A. Bates, M.D., said, "Kettering Medical Center has been a Gamma Knife customer of ours for many years. We are pleased that our creative financing solutions have made possible this upgrade to next-generation radiosurgery technology at an affordable price."

About Leksell Gamma Knife Perfexion

Leksell Gamma Knife Perfexion maintains full clinical compatibility with the classic Leksell Gamma Knife and is supported by efficacy and outcome data from 400,000 treated patients worldwide and thousands of peer-reviewed scientific articles, making it a proven choice for radiosurgery of the brain. According to Elekta, Leksell Gamma Knife Perfexion reduces unwanted body dose to the patient by up to 100 times compared with competing technologies, which is particularly important for treatment of children and women of childbearing age, and allows for a dramatically increased treatable volume, which is expected to increase the number of patients that can benefit from Gamma Knife surgery. Elekta estimates that the fully automated and efficient single push-button approach can save 3-5 working weeks of physician time per year at an average Gamma Knife center.
