摘要：
A radiation imaging apparatus including conversion elements acquiring a radiation image and detectors, a readout unit and a controller is provided. In a first operation, the controller causes the readout unit to output a composition signal obtained by composing signals from the detectors, detects irradiation with radiation based on the composition signal, and shifts to a second operation. In the second operation, the controller acquires first signals individually read out from the detectors, decides a signal component, of the composition signal, which is output from a selected detector of the detectors in accordance with a ratio of the first signal from the selected detector to a sum of the first signals, and acquires an integrated dose of radiation incident on the selected detector based on the signal component and the first signal of the selected detector.
