摘　　要：为了自动判别造影图像中的血管终端、血管段、血管分支和两血管交叉等结构模式,提出了Gabor滤波器结合圆周探测的新方法。利用该方法进行血管的逐点顺序识别时,不易受血管径向强度变化和血管弯曲的影响。研究的意义在于:一方面能够为二维造影图像中血管树的量化描述和重建血管三结构提供有益的帮助,另一方面能够为血管疾病诊断提供基本的线索。实验分别用模拟图像和血管造影图像验证该方法,获得了满意的效果。To automatically infer the patterns of vessel structure such as the distal ends,segments,bifurvessel structures,and crossing of two vessels in X-ray angiographic images,a novel method is presented based on Gabor filter and circle detector.The method can cope with varying vessel curvature and intensity feature occur along the longitudinal vessel direction.The present study can facilitate 2-D quantitative description of vessel tree and 3-D vessel reconstruction,and provide an elementary clue for the diagnostics.The proposed method has been successively applied to both synthetic images for validation purposes and the actual angiographic images,which yielded encouraging results.
