1. A method for three dimensional (3D) segmentation of an object, comprising:

  • obtain a volumetric data set containing object data and non-object data in proximity to said object data, said object data having a reference axis extending through said object data;

    defining at least one reference slice and multiple object slices within said volumetric data set, said reference slice and said object slices intersecting one another along said reference axis and containing said reference axis;

    determining, within said reference slice, reference points at edges of said object data;

    generating an estimated contour extended through said reference and object slices based on said reference points, said estimated contour intersecting said object slices to define estimated contour points; and

    adjusting said estimated contour points until corresponding substantially to actual contour points of the object data.
