    摘要： An example particle therapy system includes a toroid-shaped gantry having a central axis. The toroid-shaped gantry has a cover. The cover includes one or more segments that are rotatable at least partly around the central axis of the toroid-shaped gantry to create an unobstructed opening in the toroid-shaped gantry. The particle therapy system includes a patient couch configured to move relative to a hole in the toroid-shaped gantry, an imaging system coupled to an interior of the toroid-shaped gantry and configured for rotation about the hole in the toroid-shaped gantry, where the imaging system is configured to capture images of a patient on the patient couch, and a nozzle coupled to the interior of the toroid-shaped gantry and configured for rotation about the hole in the toroid-shaped gantry. The nozzle is configured to deliver radiation to a target in the patient based on one or more of the images.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.
