    Abstract: An example system includes a particle accelerator to produce a particle beam to treat a patient and a carrier having openings including a first opening and a second opening. The carrier is made of a material that inhibits transmission of the particle beam and the carrier is located between the particle accelerator and the patient. A control system is configured to control movement of the particle beam to the first opening to enable at least part of the particle beam to reach the patient, to change an energy of the particle beam while the particle beam remains stationary at the first opening, and to control movement of the particle beam from the first opening to the second opening. The example system also includes an energy degrader that includes at least some boron carbide.

    Abstract: An example particle therapy system includes a particle accelerator to output a particle beam having a spot size; a scanning system for the particle accelerator to scan the particle beam in two dimensions across at least part of a treatment area of an irradiation target; and an adaptive aperture between the scanning system and the irradiation target. The adaptive aperture includes structures that are movable relative to the irradiation target to approximate a shape to trim part of the treatment area. The part of the treatment area has a size that is based on an area of the spot size.

    Abstract: An example particle therapy system includes a particle beam output device to direct output of a particle beam; a treatment couch to support a patient containing an irradiation target, with the treatment couch being configured for movement; a movable device on which the particle beam output device is mounted for movement relative to the treatment couch; and a control system to provide automated control of at least one of the movable device or the treatment couch to position at least one of the particle beam or the irradiation target for treatment of the irradiation target with the particle beam and, following the treatment of the irradiation target with the particle beam, to provide automated control of at least one of the movable device or the treatment couch to reposition at least one of the particle beam or the irradiation target for additional treatment of the irradiation target with the particle beam.

    Abstract: 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.
