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: In an example, a synchrocyclotron includes a particle source to provide pulses of ionized plasma to a cavity; a voltage source to provide a radio frequency (RF) voltage to the cavity to accelerate particles from the plasma column outwardly; and an extraction channel to receive a beam of particles from the cavity for output from the particle accelerator. The particle source is configured to control pulse widths of the ionized plasma in order to control an intensity of the beam of particles. This example synchrocyclotron may include one or more of the following features, either alone or in combination.

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 method includes: receiving, from a treatment planning process, information that is based on a dose distribution for an irradiation target; and performing at least one of the following operations: moving structures to trim spots of a particle beam so that the spots of the particle beam approximate pre-trimmed spots for which characteristics are obtained based on the information received; moving structures to produce a trimming curve for a layer of an irradiation target based on a specification of a trimming curve for the layer included in the information received; moving structures to produce a single trimming curve for all radiation fields of an irradiation target based on specifications of the single trimming curve included in the information received; or moving structures based on configuration information for the structures in the information received.

Abstract: An example method of treating a target using particle beam includes directing the particle beam along a path at least part-way through the target, and controlling an energy of the particle beam while the particle beam is directed along the path so that the particle beam treats at least interior portions of the target that are located along the path. While the particle beam is directed along the path, the particle beam delivers a dose of radiation to the target that exceeds one (1) Gray-per-second for a duration of less than five (5) seconds. A treatment plan may be generated to perform the method.

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.
