Claim:
1. A planning method for a scanning method for determining an irradiation plan, the planning method comprising: identifying a planning data record representing a target volume to be irradiated and generated by an imaging, device; specifying the target volume to be irradiated and a condition to be fulfilled, the target volume having a size and a shape; implementing a first optimization that comprises: providing a first data record, providing the first data record comprising generating the first data record from the planning data record generated by the imaging device; mapping the target volume having the size and the shape in the first data record; and determining a first parameter set for irradiation planning by implementing a first optimization algorithm, in which the first parameter set is optimized with respect to the condition to be fulfilled using the first data record; implementing a second optimization that comprises: providing a second data record, which has a higher resolution than the first data record, providing the second data record comprising generating the second data record from the planning data record generated by the imaging device; mapping the target volume having the size and the shape in the second data record; and determining a second parameter set for the irradiation planning by implementing a second optimization algorithm, the implementing of the second optimization algorithm comprising optimizing the second parameter set with respect to the condition to be fulfilled using the second data record and the first parameter set; generating an irradiation planning data record using the second parameter set; and successively controlling a particle beam to destinations in the target volume based on the irradiation planning data record.
