The qualitative positron emission tomography for the dose monitoring in ion beam therapy (PT-PET) has been approved for static tumors under clinical conditions. The detection of dose deviations is based on a comparison between the measured and an anticipated β⁺-activity distribution. Also for intra-fractionally moving targets, the 4D simulation as well as the 4D reconstruction of in-beam PET data has been established. Within dedicated experiments the results of the comparison between measured and anticipated activities were investigated with regard to the detection of failures in the motion mitigated ion beam delivery.
