AMERICAN SHARED HOSPITAL SERVICES (NYSE MKT:AMS), a leading provider of
turnkey technology solutions for advanced radiosurgical and radiation therapy
services, announced today that the government of Turkey has approved
reimbursement under the country’s health insurance program for treatment with
the Gamma Knife^® Perfexion^TM system at Florence Nightingale Hospital Group
in Istanbul supplied by AMS through its EWRS Turkey subsidiary. This Perfexion
system began treating private pay patients in May 2012.

Reimbursement had previously been approved for treatments with the Gamma Knife
system at Baskent University in Adana, Turkey supplied by AMS.
