AMERICAN SHARED HOSPITAL SERVICES

REPORTS FOURTH QUARTER AND 2008 RESULTS

San Francisco, CA, March 13, 2009 AMERICAN SHARED HOSPITAL SERVICES (AMEX:AMS), a leading

provider of turnkey technology solutions for advanced radiosurgical and radiation therapy services,

today announced financial results for the fourth quarter and 2008.

Fourth Quarter Results

For the three months ended December 31, 2008, revenue was $4,740,000. This compares to revenue for

the fourth quarter of 2007 of $8,311,000, which included $3,200,000 from the sale of equipment to a

clinical partner whose lease agreement on a Gamma Knife expired under its terms in January 2008.

The decrease in revenue for the fourth quarter of 2008 versus the fourth quarter of 2007, net of

revenue from the asset sale, reflected the planned reduction in Gamma Knifes in operation at

clinical partner sites, partially offset by a 5% increase in revenue for units in operation more

Net income for the fourth quarter of 2008 was $83,000, or $0.02 per diluted share. This compares

to net income of $178,000, or $0.04 per diluted share, for the fourth quarter of 2007.

Cash flow, as measured by earnings before interest, taxes, depreciation and amortization (EBITDA),

was $2,513,000 for the fourth quarter of 2008 and $9,811,000 for the year as a whole, compared to

EBITDA of $2,403,000 and $9,405,000 for the fourth quarter and 2007, respectively.

At December 31, 2008, AMS reported cash, cash equivalents and short and long-term securities of

$10,286,000. This compares to cash, cash equivalents and short and long-term securities of

$10,010,000 at December 31, 2007. Shareholders equity at December 31, 2008 was $19,728,000, or

$4.19 per outstanding share. This compares to shareholders equity at December 31, 2007 of

$19,540,000, or $3.89 per outstanding share.

The Company repurchased 315,904 of its common shares during the fourth quarter of 2008 for an

average purchase price of $1.40 per share, reducing the number of common shares outstanding to

4,712,183 at December 31, 2008 from 5,026,587 at December 31, 2007.

For the twelve months ended December 31, 2008, revenue decreased to $19,099,000 compared to

$22,622,000 for 2007, which included $3,200,000 from the asset sale mentioned above.

Net income for 2008 was $477,000, or $0.10 per diluted share. This compares to net income of

$951,000, or $0.19 per diluted share, for 2007.

We were pleased to deliver a profit for 2008 our tenth consecutive profitable year and strong

cash flow during these difficult economic times, even as we transition our portfolio of

radiosurgical and radiation therapy assets to next-generation devices for radiation oncology

delivery. Financing requests from current and potential clinical partners remain strong for the

entire range of radiation therapy equipment available today and on the horizon. In fact, we now

are exploring opportunities to apply our fee-for-service financing model internationally, following

the receipt of requests for proposals from potential clinical partners in South America, Europe and

the Middle East for the Gamma Knife Perfexion system. The compelling value proposition we offer

our clinical partners, together with our solid cash flow and balance sheet, position us to pursue

these opportunities aggressively, said Chairman and Chief Executive Officer Ernest A. Bates, M.D.

In addition to the three Perfexion systems that began treating patients at clinical partner sites

in 2008, during the year AMS also entered into an agreement with A.M. Nisar Syed Associates, a

leading radiation oncology group, to place a single-treatment-room proton beam radiation therapy

(PBRT) device at Long Beach Memorial Medical Center. In 2007, AMS announced contracts to place

single-treatment- room PBRT devices at Tufts Medical Center in Boston and Orlando Regional

Healthcare (with professional services to be provided exclusively by M.D. Anderson Cancer Center

AMS owns more radiosurgery devices than any other company in the world, and we have rapidly

emerged as a global leader in the PBRT market, the next evolutionary step in the radiation

treatment of cancer, Dr. Bates said.

Still River Systems, developer of the Monarch250, an affordable, precise and compact proton therapy

system for cancer treatment in which AMS owns an equity interest, recently announced the successful

operation of the world s highest field, high energy cyclotron magnet. Still River s magnet is the

key technical element for reducing the size and cost of the particle accelerator that will deliver

proton therapy at a number of hospitals, beginning this fall with the first installation at Barnes

Jewish Hospital in St. Louis. Proton therapy is attracting unprecedented interest from the

radiation oncology and patient communities. Still River s device promises to make this advanced

therapy available to patients and affordable to hospitals that could not otherwise implement PBRT

due to the large size and high cost of multi-treatment-room systems, Dr. Bates said.

Dr. Bates added, We also recently announced plans to develop a three-treatment-room PBRT facility

in the San Francisco Bay area, and have entered into a non-binding agreement with Varian Medical

Systems under which Varian will supply proton therapy equipment for this facility. We are

evaluating potential sites and working to form a consortium of hospital partners for this project,

and we hope to begin treating patients in 2011, subject to financing and FDA approval. This Varian

three-room PBRT system, a development model we expect to repeat in other major urban settings,

complements our Still River single-room offering, which is better suited for independent hospital

projects. We are negotiating contracts to place additional PBRT systems in medical centers

throughout the country.
