冠状动脉血管的二维提取和运动跟踪

Two-Dimensional Extraction and Tracking of Coronary Arterial Vessels

提出了一种基于图像脊提取和snake模型的复合式方法来实现X射线造影图像序列中冠状动脉血管的二维提取和运动跟踪,并分别对临床采集图像序列和模拟图像进行了实验。结果说明,与经典模型相比本算法自动化程度和精度都提高许多。

A composite method based on image ridge detection and active contour model （snakes） for extracting and tracking dynamic coronary arterial vessels from X-ray angiographic sequences is presented. The performance and effectiveness are demonstrated on clinical coronary angiogram sequences and simulated data. The results show that the new method has a higher automatic level and better accuracy than classic algorithms.
