Leksell and Larsson first employed proton beams coming from several directions into a small area into the brain, in experiments in animals and in the first treatments of human patients. In 1951, using the Uppsala University cyclotron, Leksell and the physicist and radiobiologist Borje Larsson, developed the concept of radiosurgery.
