The Leksell Gamma Knife® Society was founded by Dr. Dan Leksell in 1989 to provide a forum for Gamma Knife clinicians, physicists and researchers to exchange information, data and clinical techniques in the quest to improve patient outcome. The Society is multinational and multidisciplinary, established to drive education and collaboration and act as a hub for resources.
