摘要

A mammography apparatus includes a radiation source having a plurality of radiation tubes. The plurality of radiation tubes are disposed at a plurality of positions where the radiation is emitted to an imaging surface of a radiation detector at different irradiation angles. A correction unit corrects irradiation conditions of the radiation using a first coefficient such that the arrival dose of the radiation reaching the radiation detector is the same regardless of the irradiation angle. The first coefficient corresponds to a compression thickness of the object, indicates a rate of change in an arrival dose of the radiation depending on the irradiation angle, and is registered for each of the plurality of radiation tubes. The setting unit sets the irradiation conditions corrected by the correction unit in the radiation source.
