摘要：
The energy subtraction apparatus of the present invention comprises an image input device which inputs two or more different kinds of radiographic images having been taken by irradiating a subject with radiation rays with different radiation qualities, an information of body part acquisition device which designates a information of body part, a motion compensation processing device which performs a registration process by compensating for shift between corresponding points between the two or more different kinds of radiographic images due to movement of the subject, a subtraction device which performs an energy subtraction process on the two or more different kinds of radiographic images, and an operation mode switching device which switches an operation mode of the registration process at the motion compensation processing device depending on the information of body part.
