About American Shared Hospital Services and the Gamma Knife

American Shared Hospital Services is building a profitable medical services company in an underserved niche -- turnkey technology solutions for advanced radiosurgical procedures. The Company’s core business is supplying hospitals with the Gamma Knife -- a non- invasive treatment for malignant and benign brain tumors, vascular malformations and trigeminal neuralgia (facial pain). The Gamma Knife, the gold standard in radiosurgery, reduces surgical risk and patient discomfort, resulting in a shorter hospital stay and lower risk of complications. In most cases, Gamma Knife patients resume their normal activities within a few days of treatment, compared to weeks or months for patients who undergo conventional surgery. More than 250,000 patients worldwide have already received this treatment. American Shared Hospital Services is the world leader in providing Gamma Knife radiosurgery services.
