History of Gamma Knife |
|
|
|
The principles behind the development of the Gamma Knife were first conceived by a Swedish neurosurgeon, Lars Leksell, during the 1950s. He envisioned a multi-source Gamma ray emitter that would be able to focus very accurately on an intracranial target and thus replace open surgery for some conditions. In 1967, the first Gamma Knife unit was put into clinical use in Karolinska, Stockholm. Almost twenty years later, the first Gamma Knife unit was opened in the United States. Since then, a number of other sites have been opened in recognition of the benefit for patients with certain intracranial conditions when Gamma Knife radiotherapy is administered.
