摘　　要：耳鼻喉头颈外科医师是通过对人体颞骨进行实体解剖,来训练耳外科手术,由于解剖教学用颞骨标本来源很有限,因此,基于虚拟现实技术的耳显微外科仿真系统对年轻医师的手术操作技能培训,术前的预测与术中的辅助都具有广阔的应用价值。该文设计并开发一种并行多图形卡工作站的分布式耳显微外科虚拟现实系统,自行建立了逼真的颞骨组织三维模型,不仅可以在虚拟环境下体验和学习耳显微手术中常见场景与处理操作,还可以实现通过网络通信进行计算机远程教学与手术会诊。Traditionally, a novice ear doctor acquires the skillfully operative ability through dissecting cadaveric temporal bone in ear surgical training lab. For conceivable reasons donated bodies are always short in supply, virtual reality-based simulator provides a new model for surgical training. It has been proven that the simulator is a useful tool for surgical training. And it can be used in the rehearsal of operation procedures, real-time operation guidance, and remote surgery. Our design is different from the existing virtual surgical system. It has a parallel, distributed multi-workstation with the vivid threedimensional model of temporal bone, and it can be used not only to learn the ear surgical skills in the virtual environment, but also preoperative plan and surgical consultation.
