<p>Provided are a radiation imaging system and radiation imaging method, wherein a system control unit comprises: a radiation imaging trial unit which, if a gradation value is different from a predicted result, exercises control by varying the irradiated energy of a radiation irradiation system so as to perform radiation imaging once; and an abnormality inferring unit which, if there is no change between the gradation value obtained from the radiation image on this one occasion and the preceding gradation value, infers that there is an abnormality in the radiation image output system and, if there is a change between the gradation value obtained from the radiation image on this one occasion and the preceding gradation value, infers that there is an abnormality in the radiation irradiation system.</p> |
