Abstract
An example particle therapy system includes: a synchrocyclotron to output a particle beam; a magnet to affect a direction of the particle beam to scan the particle beam across at least part of an irradiation target; scattering material that is configurable to change a spot size of the particle beam, where the scattering material is down-beam of the magnet relative to the synchrocyclotron; and a degrader to change an energy of the beam prior to output of the particle beam to the irradiation target, where the degrader is down-beam of the scattering material relative to the synchrocyclotron.
