1. A method for creating an irradiation plan, the method comprising:
receiving an irradiation therapy plan from a computer plan for irradiating a target with a proton beam from a gantry, the irradiation therapy plan including a plurality of irradiation spots for delivering protons to the target;
determining 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; and
generating an irradiation plan, the irradiation plan including a plurality of groups of irradiation spots based on the determined rotational profile, the slew time, and the amount of protons to be delivered to each irradiation spot, each group of irradiation spots associated with a respective portion of the angular rotation.
