目的 探讨基于内耳体素模型三维可视化膜迷路.方法 磁共振显微成像颞骨扫描影像数据使用3D Slicer软件进行表面模型体裁剪,将内耳体素模型通过表面绘制和体绘制混合成像三维显示膜迷路.结果 通过内耳体素模型可以三维可视化膜迷路,且内耳体素模型文件较表面模型文件容量更小.结论 内耳体素模型对于内耳解剖学习和研究有重要意义.“,”Objective To explore three dimensional (3D) visualization of membranous labyrinth using a voxel model.Methods 3D Slicer software was used to deal with MRI images of the temporal bone,volume clipping with the model,three-dimensional display of the membranous labyrinth by both surface rendering and volume rendering.Results With the inner voxel model we explored not only the surface of inner ear,but also the membranous labyrinth inside.The file size of inner ear voxel model file was smaller than surface model file.Conclusion Inner ear voxel model is invaluable in the study of inner ear anatomy.
