【摘要】 血管树的拓扑描述及匹配是由二维血管造影图像重建三维血管树的关键步骤,我们采用二叉树描述二维血管骨架树,提出“结点权值”和“相似结点”的概念,很好地描述了血管树的拓扑结构。同时根据二叉树的前序遍历结果匹配血管段,有效地提高了匹配的速度和准确度。更多还原

【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.更多还原
