Abstract:
Objective: To propose an automatic skeleton thinning algorithmfor accurate extracting the center line of coronary artery from CT images. Methods The region of coronary artery on CT images were segmented, and complete 3D data of coronary artery were obtained after 3D reconstruction. Then the center line of coronary artery was extracted using skeleton thinning algorithm. Dijkstra algorithm was introduced according to the characteristics of coronary artery to improve the accuracy of extraction. Results Compared with the skeleton thinning algorithm which didn't remove mini branches, the rate of overlap was increased by 2%, the average distance was reduced by 38.2%, and the average running time was 0.48 s. Conclusion Using improved skeleton thinning algorithm could effectively extract the center line of coronary arteries.
