An image processing apparatus, image processing method and image processing program

There are provided an image processing apparatus, an image processing method and an image processing program which can specify an abnormal portion of a subject easily and accurately and analyzed. An image processing apparatus 100, which is used for specifying the abnormal part of the subject, includes a calculation unit 130, the position adjusting data between contour data of a specific subject extracted from an X-ray radiographic image, and contour data of a photographic image obtained by photographing the specific subject, is calculated, a sectional image forming unit 140 that generates a sectional image of a three-dimensional X-ray CT image that is correlated with the X-ray radiographic image on a plane parallel to a light receiving surface of a correlated with the photographic image two-dimensional Biolichtbildes generated, and a display processing unit 150 indicating the three-dimensional X-ray CT image and the two-dimensional Biolichtbild superimposed on the sectional image using the calculated position adjusting.
