摘要目的 利用虚拟现实技术构建岩骨三维解剖模型,探讨其应用价值.方法 对15例尸头进行CT平扫.获得DICOM数据利用虚拟现实技术进行图像三维重建,提取并重建岩骨表面、听骨链等骨性结构三维图像,利用反转图像强度技术获得岩骨骨管和压迹内结构三维图像.在虚拟影像中测量膝状神经节、耳蜗、颈内动脉、颈静脉球、内听道外口之间距离.结果 虚拟现实三维影像能直观清楚地显示岩骨内神经、血管和骨性结构的空间关系,三维影像数据测量方便快捷,不受死角限制.结论 虚拟现实系统所构建岩骨三维解剖模型,可视化效果良好并可测量解剖数据. Objective To evaluate the application of virtual reality system in construction of 3-dimensional petrous bone model.Methods The DICOM data of the CT performed for 15 adult cadaver heads were transferred to and reconstructed in the Destroscope virtual reality system.Images were extracted to show surface of petrous bone and ossicular chain.The images of structures in osseous tube and impression of petrous bone were extracted by the skill of invert intensity.The lengths of correlated anatomical structures such as geniculate ganglion,cochlear,internal carotid artery,glomus jugulare,external aperture of inner acoustic meatus were measured in the virtual reality environment.Results Three-dimensional images could illustrate the spatial relationship of anatomic structures related to the petrous bone distinctly.The data of measure were obtained conveniently,which had no dead angles of observation.Conclusion The 3-dimentional petrous bone model constructed by virtual reality technique can be used in anatomic research with good visualization.
