【摘要】 目的作为虚拟现实在医学领域的尝试,本文利用VRML实现了基于Web的内耳解剖结构的三维可视化。方法分别对单层切片进行感兴趣区的轮廓提取,并将提取处理后的体数据导入3D Slicer,重建组织的三维表面模型,并将获得三维模型并导入VRML。结果各结构三维模型均可通过嵌入Web的VRML浏览器进行浏览,并可进行旋转、缩放等三维交互式操作。更多还原

【Abstract】 Implements 3D visualization of inner ear which is based on VR using VRML,as an attempt to use visual reality to medical domain.Extracts the contour of the interesting region in each single slice and adds the processed volumes into 3D slicer and reconstructs 3D surface model of the interested tissue,and introduces it into VRML.The result shows that D-reconstructed models can be displayed through VRML browser embedded in Web and the user can browse,rotate and zoom out or in the models.VR technology can not only be applied to 3D visualized anatomical structures,but also it is the basis to simulate medical operation.更多还原
