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 configured to output a particle beam at a predefined maximum energy and a toroidal gantry comprising magnets in an interior thereof. The magnets include a first magnet proximate to an output of the particle accelerator and second magnets proximate to a treatment position. The first magnet is configured to direct the particle beam to a second magnet. The second magnet is configured to bend the particle at the predefined maximum energy towards the treatment position.
