3-D visualization of the cholecyst and the bile duct using fuzzy clustering

摘要

This paper proposes a method for extracting the cholecyst and the bile duct from magnetic resonance cholangiography (MR-C) volumetric images. We propose weighted fuzzy c-means clustering to classify an MR-C image into some clusters in which voxels have similar intensity and similar position. Then, the method finds the clusters corresponding to the cholecyst and the bile duct by evaluating the center vectors. Our experimental result on six subjects showed that this method could extract both the cholesyst and the bile duct.
