ABSTRACT:
When the same subject is to be imaged consecutively plural times, a radiation imaging device is controlled so as to change an imaging time interval between respective imagings according to a set imaging region of the subject. When a chest portion of a subject is to be imaged, a control section designates an image obtained at a second imaging as an image for diagnosis, image quality correction processing is not performed at a first imaging, and an imaging time interval is greatly reduced compared to when other regions are imaged, thereby reducing motion artifacts of an energy subtraction image. When regions other than a chest region are imaged, the control section designates an image obtained at a first imaging as an image for diagnosis, performs image quality correction processing at the first imaging, and an imaging time interval is increased compared to when the chest region is imaged.
