Abstract

An irradiation plan for a particle irradiation unit is determined in a first run based on a specified target volume in a test object and a specified dose distribution to apply the particle beam in the target volume. The target volume includes a plurality of isoenergy layers. The irradiation plan may be determined in a second run with an additional condition that at least one of the isoenergy layers, determined according to one or more criteria, is not irradiated. Alternatively, the irradiation plan may be determined in a second run with an additional condition that only certain isoenergy layers, determined according to one or more criteria, are irradiated.
