摘要：
An example particle therapy system may include: a synchrocyclotron to produce a particle beam； a scanner to move the particle beam in one or more dimensions relative to an irradiation target； and an energy degrader that is between the scanner and the irradiation target. The energy degrader may include multiple plates that are movable relative to a path of the particle beam, with the multiple plates each being controllable to move while in the path of the particle beam and during movement of the particle beam. An aperture may be between the energy degrader and the irradiation target. The aperture being may be to trim the particle beam prior to the particle beam reaching the irradiation target.
