To produce a high-resolution, three-dimensional temporal bone model from serial sections, using a personal computer.
Digital images were acquired from histological sections of the temporal bone. Image registration, segmentation and three-dimensional volumetric reconstruction were performed using a personal computer. The model was assessed for anatomical accuracy and interactivity by otologists.
An accurate, high-resolution, three-dimensional model of the temporal bone was produced, containing structures relevant to otological surgery. The facial nerve, labyrinth, internal carotid artery, jugular bulb and all of the ossicles were seen (including the stapes footplate), together with the internal and external auditory meati. Some projections also showed the chorda tympani nerve.
A high-resolution, three-dimensional computer model of the complete temporal bone was produced using a personal computer. Because of the increasing difficulty in procuring cadaveric bones, this model could be a useful adjunct for training.
使用个人计算机从连续切片生成高分辨率的三维颞骨模型。
从颞骨组织切片获取数字图像。使用个人计算机进行图像配准、分割和三维体积重建。由耳科医生评估该模型的解剖准确性和交互性。
生成了一个准确的、高分辨率的颞骨三维模型，包含与耳科手术相关的结构。可见面神经、迷路、颈内动脉、颈静脉球以及所有听小骨（包括镫骨底板），还有内、外耳道。一些投影还显示了鼓索神经。
使用个人计算机生成了完整颞骨的高分辨率三维计算机模型。鉴于获取尸体骨骼的难度日益增加，该模型可能是培训的有用辅助工具。
