Abstract:
1. A method for executing quantitative analysis on medical image data depicting lengthwise extent of a bifurcated tubular organ comprising at least a proximal part, a first distal part and a second distal part, the method comprising: (a) processing said medical image data to identify contours of said bifurcated tubular organ along its lengthwise extent, said contours including first and second outer contours and a middle contour therebetween; (b) using said contours identified in (a) to determine a closed plane figure spanning lengthwise extent of said bifurcated tubular organ, wherein said closed plane figure is bounded by a plurality of lines meeting at vertices, the plurality of lines identifying a proximal start of said proximal part of said bifurcated tubular organ as well as distal ends of said first and second distal parts of said bifurcated tubular organ, wherein a first line of said plurality of lines lies along and follows the first outer contour as identified in (a), and wherein a second line of said plurality of lines lies along and follows the second outer contour as identified in (a); (c) using said closed plane figure to determine at least one parameter value characterizing geometry of said bifurcated tubular organ; and (d) outputting said at least one parameter value to a user.
