Abstract
A radiographic imaging apparatus acquires a plurality of two-dimensional pickup images taken at different angles and a three-dimensional image of a processing target imaged in advance. Two-dimensional calculated projection images are generated from the three-dimensional image, respectively, in association with the two-dimensional pickup images. A characteristic region indicates a treatment instrument represented in the two-dimensional pickup image. The two-dimensional pickup image is aligned with the calculated projection image. A deformation amount of the processing target in the two-dimensional pickup image is calculated by comparing the two-dimensional pickup image with the calculated projection image, and a position of the characteristic region is corrected. A three-dimensional position of the characteristic region is calculated and corrected on the basis of anatomical structure information of the processing target. A position mapping part then superimposes the corrected three-dimensional position of the characteristic region on the three-dimensional image to be displayed on a display unit.
