PROBLEM TO BE SOLVED: To provide a method of suitably correcting the detection value of each radiation dose information detector without retaking correction data used in biopsy imaging every time of stereo imaging.
SOLUTION: The radiation image capturing device includes: a plurality of AEC sensors 64 for detecting the dose of radiation Xray transmitted through the breast 28 of a subject 27 and acquiring a detection value for AEC a weighting coefficient imparting part 88 for multiplying the detection value by a weighting coefficient corresponding to the position of each AEC sensor 64 and a radiation source control part 76 for controlling the radiation dose to be exposed from a radiation source 30 on the basis of the detection value multiplied by the weighting coefficient. The radiation image capturing device is provided with: a reference value holding part 90 for holding the weighting coefficient determined on the basis of a reference geometric imaging condition as a reference weighting coefficient a geometric imaging condition acquisition part 92 for acquiring a geometric imaging condition related to the position of the radiation source 30, a solid state detector 60 or the plurality of AEC sensors 64 and a weighting coefficient correction part 94 for correcting the reference weighting coefficient on the basis of the reference geometric imaging condition, the reference weighting coefficient and the geometric imaging condition.
