Patent ID: 11794038

Abstract:
A method for creating an irradiation plan. The method may include receiving an irradiation therapy plan for irradiating a target with a proton beam from a gantry. The irradiation therapy plan may have a plurality of irradiation spots for delivering protons to the target. The method may include identifying a rotational profile for angular rotation of the gantry with respect to the target, a slew time for a proton beam to travel between each of the plurality of irradiation spots, and an amount of protons to be delivered to each irradiation spot. The method may also include creating an irradiation plan. The irradiation plan may include a plurality of groups of irradiation spots based on the rotational profile, the slew time, and the amount of protons to be delivered to each irradiation spot. Each group of irradiation spots may be associated with a respective portion of the angular rotation.
