  • THREE DIMENSIONAL IMAGE PROCESSING APPARATUS AND X-RAY DIAGNOSIS APPARATUS
    Publication number: 20100189218
    Abstract: A three dimensional image processing apparatus includes a feature point designation unit which designates feature points on at least two selected images selected from a plurality of images in different radiographing directions, a three dimensional position calculation unit which calculates a three dimensional position associated with a feature point, a two dimensional position calculation unit which calculates the two dimensional position of a feature point on an unselected image on the basis of the calculated three dimensional position of the feature point, a feature point extraction unit which extracts a feature point from an unselected image, a positional shift calculation unit which calculates a positional shift of the two dimensional position of the extracted feature point with respect to the calculated two dimensional position of the feature point, a correction unit which corrects the position of the unselected image on the basis of the calculated positional shift, and an image reconstruction unit which
