Claim One:
1. A computer-implemented method for segmenting magnetic resonance imaging (MRI) data, the method executed by a processor, the method comprising: detecting one or more edges in an image for a given bone structure; determining an initial position on the image; converting the initial position into an initial contour within the given bone structure; iteratively deforming the initial contour to expand into a shape matching the given bone structure by dynamically applying a set of constraints locally to each point along the initial contour for causing each point to evolve towards at least a selected one of the one or more edges, and updating the set of constraints after one or more iterations for each point of the contour, independently from constraints of neighboring points, wherein the set of constraints includes deformation constraints, viscosity constraints and form constraints; and outputting the segmentation data delineating the bone structure.
