title: [Topological match method in 3D reconstruction of heart vessel].
abstract: This paper presents a novel matching method of vessels in 3D reconstruction of heart vessel. The directed binary tree was used to describe the topological structure of heart vessel tree's skeleton. Based on topological property and epipolar property, the branch-points and end-points of each branch level could be automatically matched along the direction of blood stream. Thereupon it is easy to couple the corresponding vessels segments of two angiograms projected in different directions. The 3D heart vessel tree was successfully reconstructed from clinic coronary angiograms, which validates the presented method.
