PARTICLE THERAPY DEVICE AND METHOD FOR SETTING DOSE CALIBRATION FACTOR |
摘要 |
There are provided with: an irradiation apparatus (10) that radiates a particle beam after forming the beam for each of layers; a dose monitor (12) that measures a dose in real time; a dose evaluation unit (70) that evaluates an irradiation dose for each of the layers on the basis of a measurement value (C i ) measured by the dose monitor (12) and a dose calibration factor set for each of the layers; an irradiation control section (60) that performs radiation control for each of the layers on the basis of an evaluation result of the dose evaluation unit (70); and an interpolation value generation unit (74) that uses actual-measurement dose-calibration factors (± i ) each obtained by radiating a particle beam to a simulated phantom (81) provided with a calibration dosimeter (82), to thereby generate an interpolation value or an estimation value (²i) of the dose calibration factor; wherein, for each layer subject to the interpolation value or the calibration value (²i) and based on an irradiation condition of that layer, the interpolation value generation unit (74) performs weighting on each of the actual-measurement dose-calibration factors (± i ). |
