基于CT增强连续扫描数据的颅面部血管三维重建数字化模型****

背景：通过三维重建技术，可以对人体的任何一个部位进行可视化观察，但国内外基于个人PC的颅面部血管三维重建研究报道尚少。 目的：探讨基于CT增强扫描数据重建颅面部血管三维数字化模型的方法及其应用价值。 方法：选择1例经CT增强连续扫描检查的健康志愿者数据集，以DICOM格式导入 Mimics10.01软件，运用阈值选取技术、手动编辑技术、三维区域增长技术对颅面部血管进行三维重建。 结果与结论：获得了颅面部血管的三维数字化模型。该模型可以进行任意缩放和任意角度旋转，可显示不同结构间的毗邻关系和空间构象，并可进行三维的距离、角度测量。提示在PC上应用Mimics软件可以方便快捷地建立颅面部血管的三维数字化模型，为人体解剖学教学、临床神经外科、口腔颌面外科和影像诊断学提供了形态学参考，并为后期的虚拟手术奠定了基础。

Study on three dimensional reconstruction of craniofacial vascularity based on the data of CT strengthening scanning

BACKGROUND: Using three dimensional (3D) reconstruction techniques, any part of body is accessible to visual observation. However, reports concerning 3D reconstruction of craniofacial vascularity based on PC are few in China. OBJECTIVE: To explore the method and the application values of reconstructing a digital 3D model of craniofacial vascularity based on the data of CT strengthening scanning. METHODS: CT strengthening scan images from a healthy volunteer in DICOM format were imported into Mimics10.01 software and craniofacial blood vessels were reconstructed with the technique of thresholding, editing and 3D region growing. RESULTS AND CONCLUSION: The 3D digital model of craniofacial blood vessels was obtained. This model could be zoomed and rotated randomly and displayed the spatial positions and adjacent relationships of different anatomical structures, also the reconstructed structures could be measured in 3D space. The 3D digital model of craniofacial blood vessels can be reconstructed conveniently and quickly with Mimics software on PC, and also it can bring morphological reference to human anatomy teaching, clinical neurosurgery, oral and maxillofacial surgery, as well as image diagnosis, and will be helpful to generate a virtual plateform in craniofacial surgery.
