Welcome to the World of Leksell Gamma Knife Perfexion
Radiosurgery was coined by Dr Lars Leksell in 1951. He defined Radiosurgery as “delivery of a single, high dose of irradiation to a small and critically located intra-cranial volume through the intact skull ”. He called this technique "Stereotactic Radiosurgery." The first Stereotactic Gamma Knife using cobalt-60 sources was constructed and installed in Sophiahammet, Stockholm in 1968. That unit was primarily intended for use in functional brain surgery for the section of deep fiber tracts as in the treatment of intractable pain and movement disorders.
