Our unit was installed and became operational in June of 1996, and we have treated over 550 patients with intracranial lesions or functional disorders on this unit. Historically, the Gamma Knife represents the first radiosurgery instrument developed originally in Sweden by Dr. Lars Leksell in 1950. Based on the principle of precise intracranial localization utilizing a cartesian coordinate system, Dr. Leksell designed a fixed hemisperical array of Cobalt sources which emmited gamma rays to one precise point in space.
