The method involves determining irradiation areas i.e. tumor areas, in a user (1105). The user is irradiated with irradiation beams from different directions. Total dose conditions are determined, and the irradiation areas are associated to one of the total dose conditions. Single beam dose conditions are determined, where one of the beam dose conditions is associated with one of the beams and one of the irradiation areas. Exposure parameters are determined for the beams depending on the total dose conditions and the single beam dose conditions. The total dose condition is a maximum dose, a minimum dose, a dose volume histogram, an average dose, an equivalent uniform dose, a biological target or dose homogeneity. The single-beam dose condition is a maximum dose, a minimum dose or medium dose or dose homogeneity. Independent claims are also included for the following: (1) a device for determining a treatment plan for irradiation of an irradiation object (2) a particle irradiation system (3) a computer program product comprising a program stored in a storage of a processing unit (4) an electronically readable medium comprising control information. |
