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.
A tomosynthesis imaging apparatus comprising:
A method for operating a tomosynthesis imaging apparatus comprising a radiation detector that detects radiation transmitted through an object and has an imaging surface capturing a projection image of the object, the method comprising:
A non-transitory computer-readable storage medium storing a program for operating a tomosynthesis imaging apparatus comprising a radiation detector that detects radiation transmitted through an object and has an imaging surface capturing a projection image of the object and a radiation source having a plurality of radiation tubes disposed at a plurality of positions where the radiation is emitted to the imaging surface at different irradiation angles, the program causing a computer to function as:
