| 摘 要： | 为辅助医生临床诊断,提出了一种冠状动脉血管树的提取方法。提取方法包含基于形态学的冠状动脉路径线提取;基于圆模板的冠状动脉段的区域划分;基于动态规划方法的冠状动脉树边缘提取。该方法可以在无人工干预的情况下自动获取完整、单连通和单像素的冠脉树边缘。实验结果表明,与已有的获取冠状动脉树边缘方法相比较,该方法有很好的准确性。

| Abstract: | Vessel borders need to be accurately identified to aid clinical diagnoses for cardiovascular disease.An automated morphological dynamic programming method was developed to identify the coronary arterial wall.The method includes path extraction using morphological segmentation,region partitioning using a circle template,and edge detection using dynamic programming.Experimental tests gave very good results.The results show that the method more effectively detects integrated and single-pixel edges of coronary arterial trees than previous methods with no artificial intervention automatically. |
