Abstract: This paper proposes a method based on Fast Marching to extract coronary artery centerline. In the method, firstly, the original image is down-sampled; secondly, the vessel enhancing diffusion filter is used to reduce noise and increase the vessel structure; thirdly, Fast Marching algorithm is used to extract the minimal path of the initial points in down-sampled image; finally, the centerline in the original image is calculated by using minimal path. The paper uses the common data set to evaluate the method.

Key words: coronary artery, centerline extraction, coronary CTA

摘要：

提出了一种冠状动脉中心线的提取方法, 该方法以Fast Marching(快速行进)算法为基础, 首先对图像进行下采样, 接着使用血管增强滤波器对图像进行滤波, 然后利用Fast Marching算法提取下采样图像中初始点之间的最短路径, 并使用最短路径在原始图像上计算冠状动脉中心线。在公共数据集上的验证实验表明, 该方法具有较好的鲁棒性和准确性。
