1. A method of linking geometry obtained from at least one image of at least one blood vessel, the geometry including a plurality of locations in the at least one image determined to be associated with voxels representing the centerline of a vessel, each of the plurality of locations having an associated orientation indicative of a direction of a centerline of the vessel and an associated filter response resulting from applying a centerline filter centered at the respective location, the method comprising: selecting a target location from the plurality of locations; and comparing the target location with each other location in the plurality of locations within a predetermined neighborhood, wherein comparing includes: determining a distance between the target location and each of the other locations; determining a difference between the orientation at the target location and the orientation at each of the other plurality of locations; and determining a difference between the filter response at the target location and the filter response at each of the other plurality of locations; and linking the voxel associated with the target location with the voxel associated with one of the other locations based, at least in part, on the comparison.
