Abstract
A method generates a three dimensional (3D) model of a tubular organ having an occluded segment. The occluded segment adjoins a proximal segment at a proximal end thereof, and a distal segment at a distal end thereof. The procedures included injecting a first dye injection into the tubular organ, the first dye approaching a first end of the occluded segment. Multiple first-injection two-dimensional (2D) images of the tubular organ are acquired, each acquired from a different perspective, the first-injection 2D images further acquired with a respective organ timing signal reading. A second dye is injected into the tubular organ, the second dye approaching a second end of the occluded segment. Multiple second-injection 2D images are acquired of the tubular organ, each acquired from a different perspective, the second-injection 2D images further acquired with a respective organ timing signal reading. Superimposed 2D images are generated, one for each of the perspectives, each of the superimposed 2D images including the proximal segment and the distal segment. The boundary regions of the proximal segment and the distal segment in the superimposed 2D images are determined. The boundary regions of the occluded segment in the superimposed 2D images are determined by interpolating between the boundary regions of the proximal segment and the distal segment. A 3D model of the tubular organ from the superimposed 2D images is generated and a 3D center line of the tubular organ is determined, the 3D center line passing through the proximal segment, through the occluded segment and through the distal segment.
