1. A particle therapy system that irradiates a subject with a particle beam, the particle therapy system comprising:
a dose monitor that measures a dose of the particle beam;
a position monitor that measures a beam size of the particle beam; and
an irradiation control apparatus that calculates a measurement characteristic of the dose monitor based on the dose and the beam size, and controls irradiation of the subject with the particle beam based on the measurement characteristic and the dose, wherein
the irradiation control apparatus calculates a corrected dose obtained by correcting the dose based on the measurement characteristic, and performs processing of ending the irradiation with the particle beam in a case where an integral value of the corrected dose has reached the target dose, or
the irradiation control apparatus calculates a corrected target dose obtained by correcting a predetermined target dose based on the measurement characteristic, and performs processing of ending the irradiation with the particle beam in a case where an integral value of the dose has reached the corrected target dose.
