Abstract
A dose calculation apparatus includes a specifying unit that specifies physical shape information of at least one of a body width and a body thickness of a subject using a ray-sum image generated from a plurality of medical images acquired by imaging the subject with an X-ray apparatus, an acquisition unit that acquires a correction coefficient corresponding to the physical shape information of at least one of the body width and the body thickness specified by the specifying unit from a storage unit configured to store a relationship between the physical shape information and the correction coefficient, and a calculation unit that calculates dose in accordance with a physical shape of the subject based on the correction coefficient acquired by the acquisition unit and a value representing X-ray intensity during taking of medical images.
