METHOD, APPARATUS AND COMPUTER PROGRAM FOR 3D QUANTITATIVE BIFURCATION ANALYSIS USING A PLURALITY OF 2D ANGIOGRAPHIC IMAGES

PROBLEM TO BE SOLVED: To produce a normal 3D bifurcation model from a plurality of 2D angiographic images. SOLUTION: From a plurality of 2D angiographic images, a computer performs the following processes: (a) preparing a 3-D model based on these images, (b) defining a bifurcate area for this 3-D model, (c) preparing an area curve for this area, (d) preparing the standard area curve for this area, while restoring the 2D images, (e) preparing a normal model for this area curve, and (f) operating quantitative analysis results for this normal model on the basis of the 3-D model of the diseases comprising the normal section of the bifurcation, the border of the diseases and the center line of this bifurcation, the cross-section of a lumen located on the center line, the normal center line, and the cross-section.
