The objective of the China Digital Human Project (CDH) is to digitize and visualize the anatomical structures of human body. In the project, a database with information of morphology, physical charac-teristics and physiological function will be constructed. The raw data of CDH which was completed in the Southern Medical University is employed. In Huazhong University of Science and Technology (HUST), the frozen section images are preprocessed, segmented, labeled in accordance with the major organs and tissues of human beings, and reconstructed into three-dimensional (3D) models in parallel on high performance computing clusters (HPC). Some visualization software for 2D atlas and 3D mod-els are developed based on the new dataset with high resolution (0.1mm×0.1mm×0.2mm). In order to share, release and popularize the above work, a website (www.vch.org.cn) is online. The dataset is one of the most important parts in the national information database and the medical infrastructure.

目的探讨构建在体女性盆腔动脉血管网数字化三维模型的方法及意义。方法基于双源CT血管成像(CTA)技术,获取1例子宫腺肌病患者的D icom 3.0原始二维断层图像数据集。利用M im ics10.01软件分别对骨盆、盆腔动脉血管网进行三维重建并配准融合。结果构建的在体女性盆腔动脉血管网数字化三维模型可以清楚地显示髂总动脉、髂外动脉、髂内动脉及其多级分支,甚至子宫动脉上行支等。与重建的骨盆配准融合后,各支动脉血管的解剖走行及供血范围变得更加清晰明确。结论基于CTA数据集,应用适当的计算机软件可构建出理想的在体女性盆腔动脉血管网数字化三维模型,为术前手术模拟"真人化"以及数字模型物理化提供了平台。
