PROBLEM TO BE SOLVED: To optimize the dose of radiation repeatedly applied to a subject in the tomosynthesis radiography. SOLUTION: The radiographic imaging apparatus comprises a radiographic stand 24, a radiation detector 241, and a movable radiation source 26 disposed to face the radiation detector 241 with the subject M in-between. A radiation source controller 53 disposes the radiation source 26 at a plurality of positions P1-P5 so that the incident angles of radiation to the subject M are different. The radiation source controller 53 applies radiation after determining conditions for generating radiation at the respective positions based on the incident anglesθi (1≤i≤n) of the radiation to the subject at the respective positions.
