A Generalized Cylinder based on Method for Modeling Cerebral Vessel Tree
Limin Luo · Journal of Biomedical Engineering Research · 2007
Models fitting cerebral vessel's tree-like structure can improve the precision of diagnosis.An adaptive filter was used to extract vessel contours in each slice and vessels with Generalized Cylinder Model was simplified.Based on distance transformation,the centerline of vessel tree was extracted and it was traced to distinguish the bifurcation points and segment points.A fast smooth filter was applied to enhance the centerline.At last,combined with vessel radius information,the vessel surfaces was rendered.The result show that our method is useful and the constructed cerebral vessel tree has good spatial information.
