Abstract:
Medical imaging techniques produce volumetric images capturing biological structures in three-dimensions, often in the grayscale domain, where each value represents a density (or probability) of the underlying structure. Computer-based analysis of these structures is non-trivial and benefits greatly with the use of a skeletal structure consisting of centerlines. For example, skeletons of blood vessel networks (Figure 1) and lung airways can be used to determine thickness, blockages and abnormalities within those structures.
