摘要:

解剖图谱在医学教育中一直占据非常重要的地位,然而传统图谱空间信息不足,现有电子图谱图像失真且交互性差。运用虚拟现实技术开发交互性强的三维人体解剖学图谱,首先利用CT设备扫描的真实人体断层数据进行三维重建,获得结构完整的人体局部解剖三维模型;然后基于解剖学知识区分不同结构并利用3DSMAX建立骨骼、血管等独立模型并设置贴图,再导入Virtools中,配以文字、图片等多媒体材料,设置丰富的人机交互手段;最后打包生成可在Windows下直接使用的三维图谱软件。将支持游戏开发的三维引擎用于人体解剖图谱的制作中,强调其交互的丰富性,同时具有真实感强、开发周期短等优点,图谱软件有利于课堂施教和学生自学。

Abstract:

The anatomy atlas plays an important role in the medical education, but the traditional atlas cannot provide enough 3D information, and the existing electronic atlases have poor visions and interactions. A 3D human anatomy atlas focusing on interaction is developed with the virtual reality technology. Firstly, the 3D regional models are reconstructed with the CT scanning data from the real human specimen. Secondly, the different structures such as bones and vessels are distinguished and mapped with textures in 3DSMAX, and then interactions are set with other materials such as texts and pictures in Virtools. Finally, a 3D atlas is published as an independent software that can be executed in Windows OS. The 3D game engine is used to do the atlas so that rich interactions are available. The atlas owns strong realistic visions but a short development period, and will be beneficial for teaching or selflearning.
