Abstract:
A segmentation method in a computer system, comprising:receiving a plurality of digital images representing consecutive slices of a structure; said structure including a substructure; thresholding said plurality of images; dividing said plurality of images in at least one group of images; for each of said at least one group of images, a) estimating a substructure center position corresponding to said group; b) using said substructure center position to find pixels of the substructure common to all images in said group; c) for each image in said group, c1) using said group substructure center position and said substructure common pixels to estimate a substructure center position corresponding to said image; and c2) using said image substructure center position to remove noise both outside and inside said substructure, thereby producing segmented images.
