Abstract

A method for irradiation planning for a quasi-cyclically moving target volume includes defining a first movement phase within a movement period of the target volume and carrying out a first irradiation planning using a first position of the target volume during the first movement phase. The method also includes defining a second movement phase within the movement period of the target volume, and carrying out a second irradiation planning for the second movement phase using a second position of the target volume during the second movement phase. An apportionment of a total dose to be applied is provided to a first partial dose that is allocated to the first movement phase and to a second partial dose that is allocated to the second movement phase.
