1. A method of propagating parameterization in a digital medical image data set, comprising:
- providing an initial parameterization in said digital medical image data set along at least one path;
propagating a parameterization from said path, wherein said propagation is limited to being in a direction substantially parallel to said at least one path and to have a gradient which is substantially perpendicular to a gradient of a path cost associated with said propagation.

Abstract
A method of centerline determination for a tubular tissue in a medical image data set defined in a data space, comprising receiving at least one start point and one end point inside a tubular tissue volume; automatically determining a path between said points that remains inside said volume; automatically segmenting said tubular tissue using said path; and automatically determining a centerline for said tubular tissue from said segmentation, wherein said receiving, said determining a path and said segmenting, said determining a centerline are all performed on a same data space of said medical image data set.
