Abstract:
1. A radiographic image capturing system comprising: a radiation output device housing therein at least two radiation sources for emitting radiation; a radiation detecting device for detecting radiation that has passed through a subject and converting the detected radiation into a radiographic image, in a case where each of the at least two radiation sources applies the radiation to the subject; and a control device for controlling the radiation output device and the radiation detecting device, wherein the control device carries out prescribed weighting of doses of radiation to be emitted from the at least two radiation sources, and controls the radiation output device to apply the doses of the radiation from the at least two radiation sources to the subject in accordance with the weighting; wherein the radiation output device houses therein at least three radiation sources; the at least three radiation sources are grouped into at least three groups each including at least one of the radiation sources; the control device carries out, with respect to the groups, the weighting of the doses of radiation to be emitted from the at least three radiation sources, such that the dose of the radiation emitted from the radiation source included in the group positioned near a geometric center position of the at least three radiation sources is of a maximum dose level, and the doses of radiation emitted from the radiation sources included in the groups other than the group positioned near the geometric center position are of a lower dose level of a degree for supplementing the maximum dose level; and the control device controls the radiation output device to apply the radiation to the subject from the at least three radiation sources in accordance with the weighting.
