Sun Zhen · Beijing shengwu yixue gongcheng · 2006
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.
