title: [Study on topological description and matching of vessel tree].
abstract: Topological description and matching are committed steps for three-dimensional reconstruction of vessel tree from two angiograms. Binary tree is proposed to describe the two-dimensional vessel tree. "Node Weight" and "Similar Node" are defined in order to get better description. Vessel segments in two images are matched by the preorder traversal of the binary trees, and the method is proved fast and accurate.
