　　基于主颈动脉分叉点和中轴，对超声三维体数据按三视图方向切分，依次得到二维横断面、冠状面和矢状面序列图像；分别处理上述序列图像，得到最终的主颈动脉血管壁内外轮廓和血管壁厚度等信息。克服现有计算机辅助诊断中血管分割方法计算复杂度大、主观因素易造成误差等缺点，能快速、准确、完整地获得颈部超声主颈动脉血管的整体信息。与手动分割方法相比，操作快捷，可用于颈部粥样硬化以及心血管疾病的辅助诊断和防治。

An integrated segmentation method for 3D ultrasound carotid artery was proposed. 3D ultrasound image was sliced into transverse, coronal and sagittal 2D images on the carotid bifurcation point. Then, the three images were processed respectively, and the carotid artery contours and thickness were obtained finally. This paper tries to overcome the disadvantages of current computer aided diagnosis method, such as high computational complexity, easily introduced subjective errors et al. The proposed method could get the carotid artery overal information rapidly, accurately and completely. It could be transplanted into clinical usage for atherosclerosis diagnosis and prevention.
