What is the history of Gamma Radiosurgery?

Gamma Radiosurgery has successfully treated patients since 1968.

Lars Leksell, a Swedish neurosurgeon, began developing this revolutionary technology in 1945. While researching how to treat brain disorders without surgery, Dr. Leksell developed a stereotactic frame that allowed placement of a probe or electrode at precise locations within the brain. By the 1950s, Dr. Leksell had teamed with physicist Borje Larsson at the Karolinska Hospital and Institute in Stockholm. Together they researched ways to combine the stereotactic frame with exacting applications of radiation to pinpoint target masses. This new technique, named stereotactic radiosurgery, has the advantage of treating a lesion or arteriovenous malformation (AVM) with minimal effect to surrounding tissue.

The core of this advanced technology is the process of delivering sources of radiation over a spherical area of the patient's head. While each beam consists of low-dose radiation having little effect on the brain tissue that it passes through, where the beams intersect - at the target - the dosage becomes a more powerful mechanism for ameliorating lesions and malformations such as AVMs. After years of experimentation and clinical trials, Gamma Radiosurgery, also known as Stereotactic Cranial Radiosurgery, has been further refined and proven successful.
