Understanding the structure and morphology of the hepatic vessels is important for liver surgical planning. In this paper, we present a new centerline tracking method for extraction of 3D branching vascular structures with minimum user operations and acceptable processing time. The requirement for user operations in our method is to set initial tracking position and orientation.
Once they have been set, the method automatically tracks centerlines and determines branch and terminal points as well as new positions and orientations at the detected branch points for restarting the tracking. The method uses two different algorithms for detecting the vessel directions and branching points; one is based on region growing using automatically determined threshold, and the other is based on local intensity distribution analysis, which is more robust against subtle structures and used when the threshold determination is unreliable. In experiments using 14 liver CT data sets, the method could extract 80% of hepatic arteries observable in the cross-sectional images by a radiologist. |
