US Patent 10299749 Mammography device, radiographic imaging method, and program

An irradiation condition setting section 52 sets irradiation conditions corresponding to the emission angle of radiation emitted from a radiation source 26. The radiation source 26 emits radiation to a breast at a plurality of different emission angles based on the set irradiation conditions. A radiation detector 36 generates a plurality of projection images corresponding to the plurality of emission angles. An image correction section 56 corrects each projection image such that a difference between at least either contrasts or density values in the plurality of projection images is reduced. A reconstruction unit 58 reconstructs a tomographic image based on the plurality of corrected projection images.
