Patent ID: 7841772

Claim:
An imaging apparatus comprising: an X-ray imaging unit configured to capture an X-ray image of a subject by detecting X-rays, which have been generated by an X-ray source and have passed through the subject, using an X-ray detector; a half-mirror provided between the X-ray source and subject and configured to pass X-rays and reflect visible light; an optical imaging unit configured to capture an optical image of the surface of the subject, wherein the optical image has been reflected by said half-mirror; a display unit configured to display a point asymmetric reference mark, which indicates a reference position of the optical image, together with the optical image captured by said optical imaging unit, and to display, in superimposed form, an X-ray image obtained by imaging a prescribed reference object having a shape the same as that of the point asymmetric reference mark as a subject using said X-ray imaging unit; and an adjusting unit configured to adjust the position and angle of rotation of at least one of either said X-ray imaging unit or said optical imaging unit in such a manner that the reference object displayed by said display unit will coincide with the point asymmetric reference mark.
