Claim One:
1. A method for construction of a vascular tree model comprising: receiving by image processing circuitry a plurality of 2-D angiographic images showing blood vessel segments of a portion of a vasculature of a subject; extracting automatically by the image processing circuitry, from each of said plurality of 2-D angiographic images, an image feature set comprising 2-D feature positions of said blood vessel segments; and identifying homologous vascular branches among the 2-D angiographic images using said blood vessel segments, wherein the identifying comprises: adjusting automatically by the image processing circuitry said 2-D feature positions to reduce relative position error in a common 3-D coordinate system to which each said image feature set is back-projectable, and then associating automatically by the image processing circuitry image features of the image feature sets as representing homologous vascular branches, based on their projection from the planes of the 2-D angiographic images to common blood vessel segment regions in said common 3-D coordinate system.
