1. A method for segmenting an anatomical structure represented in a three-dimensional data set, the method comprising:

  • starting from a point in the three dimensional data set, growing a region in the anatomical structure by modifying coordinates of a voxel in the region to find a next generation voxel, examining a characteristic of the next generation voxel, and adding the next generation voxel to the region when the characteristic of the voxel is within a threshold; and

    growing the region with successive generations of voxels along a path in the three dimensional data set using a path length limit to limit the number of generations of voxel growth from the starting point.
