摘　　要：提出了1种用于选择性冠状动脉造影血管边缘提取的新算法。该算法首先检测血管的路径,然后再沿与血管路径垂直的方向检测血管的边缘。实验证明,血管边缘检测算法在血管交叉、分支较少的冠状动脉造影图像中对血管边缘的提取效果较好。A new method is developed to detect vascular edge-line in coronary angiograms. It firstly searches the path through vessel segment of interest, then detects vascular edges along profiles perpendicular to the path. The experiments demonstrate that the method performs well in coronary angiograms with less nearby or overlapping structures and branching vessels.
