颅颈交界区结构的三维重建

目的:建立颅颈交界区解剖结构的三维可视化模型。方法:选取首例中国数字化可视人体数据集中颞骨内耳门平面至枢椎下缘的连续薄层断面图像。运用3D-DOCTOR软件,在P4微机上分割重建颅颈交界区的解剖结构并立体显示。结果:成功重建并立体显示枕骨、颞骨、寰椎、枢椎、小脑、脑干及颈髓上段、椎动脉、颈内动脉、颈内静脉和部分硬脑膜窦等解剖结构的位置关系,建立了颅颈交界区的三维可视化模型。结论:颅颈交界区的薄层断面图像可为该区疾病的CT、MRI诊断提供参考。建立的三维可视化模型,可为颅颈交界区手术的术前训练和模拟提供形念学依据。

Three-dimensional reconstruction of structures in the craniocervical junction region

Objective:To build three-dimensional reconstruction and visualization model of the structures in the cranio- cervical junction region.Methods:Cross-sectional images from the internal acoustic pore to the inferior border of the axis were collected from the dataset of the first Chinese Visible Human.On the P4 computer,three-dimensional recon- struction of the anatomic structures in the craniocervical junction region was perforated by 3D-DOCTOR software.Re- sults:The occipital bone,temporal bone,atlas,axis,vertebral artery,internal carotid artery,internal jugular vein,brain stem and superior part of spinal cord were successfully reconstructed and displayed.Conclusion:The thin cross-section of the craniocervical junction region could provide morphologic data for imaging diagnosis of this region.The three-di- mensional model of the craniocervical junction region could provide morphologic data for preoperative training and simu- lation.
