Radiographic imaging apparatus and method for controlling the same

A non-transitory computer-storage medium storing a computer program for causing a computer to control a radiographic imaging apparatus that performs a first imaging in which radiographic imaging is performed with a first X-ray dose and a second imaging in which radiographic imaging is performed at a second X-ray dose that is less than the first X-ray dose, the computer program comprising:

• a first executing step of executing the second imaging on a periodically moving organ, wherein the first executing step executes the second imaging at plural timings in one cycle of the periodically moving organ to obtain a plurality of images;
• and
• a determining step of determining a predicted timing corresponding to a particular phase in the cycle of the periodically moving organ based on changing amounts acquired from the plurality of images obtained by the executing step, wherein the executing step executes the first imaging at the predicted timing determined by the determining step;
• and
• a second executing step of executing the first imaging at the predicted timing determined by the determining step.
