The first Gamma Knife® was developed in 1967 by Lars Leksell, a Swedish physician and professor of neurosurgery, with the assistance of biophysicist Börje Larsson. Today's Gamma Knife, manufactured by Elekta AB, is based on that early prototype, but has benefited frome more than 30 years of advancements in engineering, radiation physics, and computer imaging technology.
As a result, the Leksell Gamma Knife® is one of the world's most technologically advanced surgical instruments in use today. More than 500,000 patients already have been successfully treated with this radiosurgical device.
