利用万维网(World Wide Web，WWW)进行耳蜗三维建模和可视化是在互联网上共享耳蜗术前解剖信息的有效途径，特别是在耳鼻喉科和神经放射科的形态测量研究和住院医师培训中。本文将三维建模、可视化和动画技术以一种交互的、平台无关的方式集成在一起，并在WWW上实现。将具有人体耳蜗体平均截面积的模板形状扩展为三维几何模型。对患者耳蜗螺旋CT数据进行数字分割和几何表示。根据其规范合成耳蜗电极阵列。然后，使用理想化的和真实的耳蜗模型来制作人工耳蜗术的动画。在虚拟置入过程中，在线估计单个电极的插入长度、角位置和特征频率。为了验证该技术在临床应用的可行性，对处理参数进行了优化。
3D modeling and visualization of the cochlea using the World Wide Web (WWW) is an effective way of sharing anatomic information for cochlear implantation over the Internet, particularly for morphometry-based research and resident training in otolaryngology and neuroradiology. In this paper, 3D modeling, visualization and animation techniques are integrated in an interactive and platform-independent manner and implemented over the WWW. L.T. Cohen et al.'s (1996) template shape with mean cross-sectional areas of the human cochlea is extended into a 3D geometrical model. Also, spiral computer tomography data of a patient's cochlea is digitally segmented and geometrically represented. The cochlear electrode array is synthesized according to its specification. Then, cochlear implantation is animated with both idealized and real cochlear models. The insertion length, angular position and characteristic frequency of individual electrodes are estimated online during the virtual insertion. The optimization of the processing parameters is done to demonstrate the feasibility of this technology for clinical applications.
