Radiation imaging system, imaging control device, and storage medium
A radiation imaging system including: a radiation generator that includes a radiation source generating a radiation pulse by receiving a tube current of a preset amount; a radiation detector that includes a plurality of charge accumulators which accumulate and release electric charges to be read out as signal values according to received radiation and that generates a dynamic image formed of a plurality of frames; and a hardware processor. The hardware processor sets an amount of the tube current and a length of an accumulation time for which the charge accumulators are allowed to accumulate the electric charges, calculates such a proper range of the tube current that start and end of generation of one radiation pulse by the radiation generator are within one accumulation time to perform an imaging with the accumulation time, and regulates setting of a value out of the proper range.
