Patent ID: 8809814

Claim:
A method for irradiation planning for a target volume, the method comprising: defining, with a computer unit, a target region having a plurality of target points, the plurality of target points being individually approachable; defining, with the computer unit, a number of rescanning passes, in which the target region is scanned multiple times, such that the plurality of target points of the target region is approached variously often during the rescanning passes, so that at least some target points of the plurality of target points are not approached in each rescanning pass; generating an irradiation plan based on the defined rescanning passes; and sending the generated irradiation plan to an irradiaiton system, the generated irradiation plan being executable by the irradiation system, wherein the approaching of the plurality of target points is distributed among the rescanning passes such that for at least one target point of the plurality of target points that is not approached in each rescanning pass, at least one further rescanning pass, in which the at least one target point is not approached, is located before a final rescanning pass, in which the at least one target point is approached.
