摘要
利用心血管造影图像定量描述心血管病变和重建三维心血管 ,首要任务是将造影图像中的心血管表述成单个象素宽的心血管骨架 ,而心血管的提取又是心血管骨架提取和决定其提取准确性的关键。首先采用了旋转高斯函数对图像进行增强 ,然后提出了自适应跟踪圆模板对增强后的心血管图像进行心血管提取。该提取方法与以往的提取方法相比 ,鲁棒性增强 ,为心血管骨架提取、心血管病变的定量描述和心血管三维重建奠定了基础。
Quantitative description and 3-D reconstruction of heart vessels are based on thinning vessels to skeletons with only one pixel width. But vessels extraction from angiogram decides the accuracy of vessels skeletonization. In this paper, rotating Gauss function was firstly used to enhance angiogram, then self-adaptive tracking circular template was addressed to extract heart vessels from enhanced angiogram. This method is superior to the conventional. Successful vessels extraction ensures heart vessels skeletonization, disease quantitative description and 3-D reconstruction.
