PURPOSE
To develop a three-dimensional (3-D) virtual model of a human temporal bone and surrounding structures.
METHODS
A fresh-frozen human temporal bone was serially sectioned and digital images of the surface of the tissue block were recorded (the 'Visible Ear'). The image stack was resampled at a final resolution of 50 x 50 x 50/100 micro m/voxel, registered in custom software and segmented in PhotoShop 7.0. The segmented image layers were imported into Amira 3.1 to generate smooth polygonal surface models.
RESULTS
The 3-D virtual model presents the structures of the middle, inner and outer ears in their surgically relevant surroundings. It is packaged within a cross-platform freeware, which allows for full rotation, visibility and transparency control, as well as the ability to slice the 3-D model open at any section. The appropriate raw image can be superimposed on the cleavage plane. The model can be downloaded at: (https://research.meei.harvard.edu/Otopathology/3dmodels/).
目的
构建人颞骨及周围结构的三维（3-D）虚拟模型。
方法
对一块新鲜冷冻的人颞骨进行连续切片，并记录组织块表面的数字图像（“可视耳”）。图像堆栈以50×50×50/100微米/体素的最终分辨率重新采样，在定制软件中配准，并在Photoshop 7.0中进行分割。分割后的图像层被导入Amira 3.1以生成光滑的多边形表面模型。
结果
该三维虚拟模型展示了中耳、内耳和外耳在与其手术相关的周围环境中的结构。它被打包在一个跨平台免费软件中，该软件允许进行全旋转、可见性和透明度控制，以及在任何截面将三维模型切开的能力。适当的原始图像可以叠加在劈开平面上。该模型可在以下网址下载：（https://research.meei.harvard.edu/Otopathology/3dmodels/）。
