摘要： PROBLEM TO BE SOLVED: To obtain an accurate PET image in a spot scanning type charged particle beam irradiation system.SOLUTION: A PET control part 49 receives an emission stop signal from an irradiation device control part 48, and starts PET measurement after the lapse of a preset fixed time (S109). When spot irradiation for a spot number j is completed, a spot position corresponding to the spot number j +1 (S111→103) is selected. For the next spot irradiation, the irradiation device control part 48 transmits an emission start signal, and the PET control part 49 stops the PET measurement when receives the emission start signal (S105). In other words, the PET measurement is performed while the emission is stopped. A PET signal obtained in the PET measurement is recorded in a memory in the PET control part 49 as PET data just before the spot irradiation for the spot number j +1. A PET image obtaining function 49a obtains the distribution of positron emitters (the PET image) from the recorded PET data.
