REPORTS THIRD QUARTER AND NINE MONTHS RESULTS

San Francisco, CA, November 14, 2007 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 third quarter and first nine months of 2007.

Third Quarter Results

For the three months ended September 30, 2007, revenue decreased 11.2% to $4,652,000 compared to

$5,238,000 for the third quarter of 2006. This reflected a decrease in procedures during this

year s third quarter versus prior year, partially due to six weeks of downtime associated with the

planned upgrade of a clinical partner site from the Gamma Knife to the new Leksell Gamma Knife

PerfexionTM system. This new system began treating patients in October 2007. With

Perfexion s increased utility compared to the Gamma Knife, we anticipate higher revenue from this

site in future quarters, said Chairman and Chief Executive Officer Ernest A. Bates, M.D. AMS

expects to upgrade three additional sites with this advanced equipment over the next several

The IGRT and related equipment and services AMS has contracted to supply another current Gamma

Knife customer began clinical operations in the third quarter. In the fourth quarter, we expect

revenue from this new IGRT contract to partially offset the impact of the recent expiration of one

of the Company s 21 existing Gamma Knife contracts. As the body radiosurgery component of this

IGRT program matures, revenue from this site should increase. We are actively pursuing additional

IGRT programs as part of our growth strategy, Dr. Bates said. He noted that a second Gamma Knife

contract is scheduled to terminate in early 2008 at the end of its term.

Reflecting lower patient volume, gross margin declined to 46.3% compared to 50.6% for the third

quarter of 2006. Selling and administrative expense decreased to $1,038,000 for the third quarter

of 2007 compared to $1,109,000 a year earlier.

Operating income for this year s third quarter was $684,000 compared to $1,000,000 for the same

period of 2006. Net income for the third quarter of 2007 was $268,000, or $0.05 per diluted share,

reflecting a 47% effective income tax rate. This compares to net income for the third quarter of

2006 of $425,000, or $0.08 per diluted share, reflecting a 40% effective income tax rate.

For the nine months ended September 30, 2007, revenue decreased to $14,311,000 compared to

$15,592,000 for the first nine months of 2006. Gross margin was 47.7% compared to 49.4% for the

The new technologies for radiation oncology delivery that are now being introduced to the market

have the potential to significantly improve patient outcomes in the treatment of many formerly

intractable cancers and other life-threatening conditions. Given the high costs involved, the

transition to these advanced treatment modalities is a substantial undertaking for the clinical

community that will take years to complete. This has created a significant long-term growth

opportunity for AMS. We are committed to helping drive the transition with our creative financing

solutions that make proton beam radiation therapy (PBRT) systems, Leksell Gamma Knife Perfexion

systems, IGRT systems, and other next-generation radiosurgery devices available and affordable to

our clinical partners across the country, Dr. Bates said.
