<p>The invention relates to the determination of control parameters for an irradiation sequence on a volume to be irradiated from an irradiation direction, the volume consisting of a multiplicity of volume elements, each of the volume elements being assigned a particle number to be applied, and the volume being greater than a maximum scanning volume determined by a scanning area of a scanning system of the therapy system, having the following method features: automatically splitting up the volume to be irradiated into a number of subvolumes, each of the subvolumes being no greater than the maximum scanning volume, and each of the volume elements being contained in at least one subvolume; automatically determining a patient position and/or patient holder position as control parameter in the case of which one of the subvolumes is arranged in the scanning area; and automatically determining a particle "sub"number for each volume element of a subvolume as control parameter such that the sum of all the particle "sub"numbers of a volume element corresponds to the required particle number of this volume element.</p> |
