PROBLEM TO BE SOLVED: To reduce imaging region setting errors due to the thickness of a subject in a radiographic image capturing system.;SOLUTION: In a radiographic image capturing system 100, when one end Pt of an imaging region is set, a rotating mechanism 15 rotates a radiation source 14 to place the radiation source in a first rotation state, and control means stores, as first position information, a position Dt2 of the radiation source adjusted by moving a first moving mechanism 13 when the first rotation state is assumed, and when the other end Pb of the imaging region is set, the rotating mechanism rotates the radiation source to place the radiation source in a second rotation state, and the control means stores, as second position information, a position Db2 of the radiation source adjusted by moving the first moving mechanism when the second rotation state is assumed. After setting the one and other ends of the imaging region, the control means determines the position of the radiation source for image capturing based on the first position information and the second position information.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
