摘要：

目的 探讨利用磁共振（MRI）原始数据集构建在体女性主韧带及宫骶韧带数字化三维模型的方法及意义。方法 选取2013年2月南方医科大学南方医院的1例健康青年女性志愿者，对其行高分辨率薄层质子密度加权MRI扫描。将采集的Dicom 3.0原始数据集导入Mimics 10.01软件中进行主韧带及宫骶韧带的三维重建。结果 成功构建了主韧带及宫骶韧带、骨盆和盆腔器官的数字化三维模型，该模型具有表面光滑、形态逼真的特点，可以进行任意角度旋转以便清楚地观察主韧带及宫骶韧带的形态及其空间毗邻关系。结论 利用薄层MRI扫描技术及计算机三维重建技术可以成功构建出在体女性主韧带及宫骶韧带的数字化三维模型，获得的数字模型可为解剖教学、定量分析提供教字化平台。

Abstract:

Abstract：Objective To explore the method and significance of three-dimensional reconstruction of cardinal ligament and uterosacral ligament in female based on magnetic resonance imaging （MRI）. Methods Select 1 healthy young female volunteers undertake the high resolution thin proton density weighted scanning. MR images were imported into Mimics 10.01 for 3D reconstruction. Results Models of cardinal ligament and uterosacral ligament and its surrounding structures were successfully built. The reconstructed model of cardinal ligament and uterosacral ligament is of clear surface and can be continuously rotated in 3D space. Using the 3D measurement tool can also do the quantitative analysis about its morphology. Conclusion Using related software like Mimics with database collected through MRI, the model of cardinal ligament and uterosacral ligament could be successfully constructed, which may provide a platform for teaching of anatomy and quantitative study of ligament.
