About

American Shared Hospital Services (AMS) is a San Francisco-based company best known for leasing specialized radiation therapy equipment to healthcare providers. It operates as a financial and service partner for advanced cancer treatment centers, focusing on stereotactic radiosurgery technology.

The company generates revenue through two main segments. The Leasing segment involves owning and leasing sophisticated equipment like Gamma Knife systems for non-invasive brain surgery and a proton beam radiation therapy system. For its leasing clients, which include hospitals and cancer treatment networks worldwide, the company also provides related support services such as treatment planning, installation, and assistance with marketing and reimbursement. Its second segment, Direct Patient Service, involves the ownership and operation of two dedicated Gamma Knife facilities where the company provides the radiosurgery procedures directly to patients.

By providing this capital-intensive equipment and related expertise, American Shared Hospital Services enables healthcare providers to offer advanced radiation oncology treatments without the full upfront capital outlay. Founded in 1980, the company has built a niche in facilitating access to these high-tech medical technologies. Its business model revolves around long-term equipment leases and the operation of its own treatment centers, serving the global market for advanced cancer care.
