Claim:
1. A computer-implemented method for active contour segmentation of imaging data, the method comprising: receiving an image of a first structure and at least a second structure; receiving a first initial position on the image for the first structure and at least a second initial position on the image for the at least second structure; setting the first initial position as a first initial contour and the at least second initial position as an at least second initial contour; and concurrently and iteratively deforming the first initial contour and the at least second initial contour to respectively expand into a first expanded contour matching a shape of the first structure and at least a second expanded contour matching a shape of the at least second structure by applying one or more constraints to each point of the first initial contour and the at least second initial contour, a selected one of the one or more constraints being applied for preventing the first initial contour and at least one of the at least second initial contour from intersecting one another upon being deformed, and updating the one or more constraints after each iteration, wherein the one or more constraints comprises one or more deformation constraints and one or more form constraints to be applied at each point along at least one of the first initial contour and the at least second initial contour.
