CT冠脉造影中冠状动脉中心线的提取

摘要

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.%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.
