摘要：

目的　探讨基于CT增强扫描数据重建股动脉插管区血管的三维数字化模型的方法及其应用。方法　采用1例股动脉插管失败病例，经CT增强连续扫描，获得数据集，以Dicom格式导入Mimics10.01软件，运用阈值选取技术、手动分割技术、三维动态区域增长技术、布尔运算技术对股动脉插管区进行三维重建。结果　按照组织层次获得了股动脉插管区皮肤、血管、髋骨的三维数字化模型，该三维模型可以进行任意缩放旋转，可显示结构间的毗邻关系和空间构象，可在三维空间进行距离、角度的测量，由此找到了股动脉插管导丝误入腹壁下动脉的原因。结论　提示在个人PC上用Mimics软件可以较为快捷地建立三维数字可视化模型，为临床介入治疗和影像诊断提供了形态学参考及个性化考量。

Abstract:

Objective　To explore the method and clinical values of a digital 3D model of femoral artery and adjacent structures based on the data of CT strengthening scanning.　Methods　 CT strengthening scan images from a patient who was failed in catheterization from femoral artery were collected. The DICOM format was imported into Mimics10.01 software, followed by femoral artery reconstruction through the technique of the thresholding,　Results　According to organization layering, 3D models, involving skin, artery and bone, were reconstructed. This model could be zoomed and rotated randomly and displayed clearly the spatial positions and adjacent relationships of different anatomical structures, as well the reconstructed structures could be measured in details in 3D space. 3D models could be used to guide catheterization from femoral artery.　Conclusions　3D digital models can be reconstructed conveniently and quickly with Mimics software on PC, which can provide morphological reference for image diagnosis and interventional therapy.
