Claim 11:
12. A radiation imaging apparatus for producing a radiographic image of a subject, comprising:
a radiation irradiation unit configured to irradiate the subject with radiation;
a radiation detection unit configured to detect the radiation emitted from the radiation irradiation unit and passed through the subject;
an orientation determination unit configured to determine that an orientation of the subject is which of an orientation for performing PA (Posterior-Anterior) imaging in which imaging is performed from behind of the subject, an orientation for performing AP (Anterior-Posterior) imaging in which imaging is performed from front of the subject, an orientation for performing LR (Left-Right) imaging in which imaging is performed from left of the subject, or an orientation for performing RL (Right-Left) imaging in which imaging is performed from right of the subject; and
an annotation processing unit configured to annotate a mark corresponding to the orientation of the subject for an X-ray image based on the orientation of the subject determined by the orientation determination unit.
