摘要
目的 探讨结合血管管状特征的胆囊动脉血管分割方法以及三维可视化胆囊三角（Calot三角）的可行性.方法 采集13例患者多层螺旋CT扫描图像,利用结合血管管状特征的三维区域生长算法,分割出胆囊动脉及与其相连的动脉血管,通过自主研发的三维重建软件CalotShow 1.0对所采集数据进行三维可视化研究.结果该方法能有效分割胆囊动脉,获得直观的Calot三角三维可视化模型.结论利用结合管状特征的胆囊动脉血管分割方法以及CalotShow1.0三维重建软件,能够准确显示胆囊动脉与Calot三角毗邻关系和空间构象.
Objective To explore the feasibility of tubular model based segmentation method for cystic artery and three-dimensional （3D） reconstruction model of Calot＇s triangle.Methods A tubular model based 3D region growing algorithm was proposed for the segmentation of cystic arteries and its adjacent vessels from 13 patients＇ CT images in DICOM format.The data was transferred to 3D visualization workstation based on a set of CalotShow1.0 software for 3D reconstruction.Results The method could effectively segment cystic artery and obtain the 3D model of Calot＇s triangle.Conclusions The 3D reconstruction model based on tubular model related vessel segmentation method and CalotShow1.0 can accurately display the spatial positions and adjacent relationships of cystic artery and Calot＇s triangle.
