Claim One:
1. A computer-implemented method for determining a three-dimensional (3D) surface reconstruction of at least one tubular vessel, the method comprising: a) generating a first 3D surface reconstruction of the at least one tubular vessel from a set of two-dimensional (2D) angiographic X-ray images of the at least one tubular vessel which have been obtained from different perspectives; b) specifying an N-furcation of the at least one tubular vessel where a proximal tubular organ branch splits into N distal tubular organ branches, wherein N is an integer greater than or equal to 2; c) determining at least one viewing direction for viewing the N-furcation of the at least one tubular vessel of b), wherein the at least one viewing direction is substantially perpendicular to a plane that extends through the proximal and distal tubular organ branches of the N-furcation of b); d) obtaining at least one 2D angiographic X-ray image of the at least one tubular vessel corresponding to the at least one viewing direction of c); and e) updating the first 3D surface reconstruction of the at least one tubular vessel by generating a second 3D surface reconstruction of the at least one tubular vessel from all or part of the set of 2D angiographic X-ray images used to generate the first 3D surface reconstruction of the at least one tubular vessel in a) and the at least one 2D angiographic X-ray image of the at least one tubular vessel obtained in d).
