Coronary artery centerline extraction in coronary CTA. Journal of Frontiers of Computer Science and Technology, 2011, 5(11): 999-1005. 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 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
