Patent ID: 8155411

Claim:
A method for analysis of a bifurcated tubular organ using multiple 2D angiographic images of the organ, said method comprising: a. Creating a first 3D model based on said images; b. Defining a bifurcation region regarding said first 3D model; c. Creating an area curve regarding said first 3D model, including c.1 deriving a 2D representation of the bifurcated tubular organ based upon said bifurcation region, said 2D representation defining a bifurcation including a main branch and two side branches, c.2 converting said 2D representation to define two respective vessels formed by splitting of the bifurcation, c.3 measuring various diameters regarding said respective vessels, and c.4 combining 2D quantities regarding said respective vessels; d. Creating a reference area curve regarding the bifurcated tubular organ whilst reconstructing in 2D; e. Creating a 3D healthy model of the bifurcated tubular organ based upon said area curves; and f. Computing quantitative analysis results regarding said 3D healthy model of the bifurcated tubular organ.
