1. A system for generating an image of at least one portion of an anatomical structure, comprising: a processing arrangement which is programmed to: receive first image data; generate second image data based at least partially on the first image data using a peel procedure with a subvoxel precision; generate third image data based at least partially on the first image data using a grow procedure with a subvoxel precision, wherein the grow procedure is based on surface voxels and connected voxel components which are associated with the surface voxels, wherein the generation of the third image is provided so as to offset processing of the surface voxels associated with the at least one portion; compare the second image data with the third image data to obtain fourth image data so as to separate anatomically distinct and adjacent sections of the at least one portion from one another; and generate the image based on the fourth image data.
