Method, Apparatus and Computer Program for Quantitative Bifurcation Analysis in 3D Using Multiple 2D Angiographic Images

A computer-implemented method (and corresponding data processing facility and computer program) for creating a 3D bifurcation healthy model from multiple 2D angiographic images comprises the following: a. Creating a 3-D model based on said images; b. Defining a bifurcation region regarding said 3D model; c. Creating an area curve regarding said region; d. Creating a reference area curve regarding said region whilst reconstructing in 2D; e. Creating a healthy model regarding said area curves; and f. Computing quantitative analysis results regarding said healthy model based on the healthy cross-sectional areas of the bifurcation, obstruction boundaries and the diseased 3D model consisting of the bifurcation centerlines and cross-sections of the lumen on the centerline, the healthy centerline and cross-sections.
