Radiation image pick-up device, radiation image pick-up method, and radiation image pick-up system

摘要

A plurality of correction images are obtained while changing the radiation energy of an incident radiation in the absence of an object. Subsequently, an object image is obtained in the presence of the object by emitting the radiation to the object. Then, the object image is corrected by using a correction image obtained under a radiation energy condition closest to the radiation energy of the obtained object image.
