目的：开发一个三维虚拟模型的人颞骨的基础上连续的组织sections.Background：三维解剖的人颞骨是复杂的，学习它是一个挑战，学生在基础科学和临床medicine.Methods：每五个组织切片从一个正常的14岁的男性被数字化，并导入到一个通用的三维渲染和分析软件包称为Amira（3.1版）。切片对齐，感兴趣的解剖结构进行segmented.Results：的三维模型是一个表面渲染这些结构的利益，目前包括骨和空气空间的颞骨;外淋巴和内淋巴空间;感觉上皮的耳蜗和前庭神经;听小骨和鼓膜;中耳肌肉;颈动脉;和耳蜗，前庭，和面神经。对于每个结构，可以单独控制表面透明度，从而揭示表面地标和底层结构之间的三维关系。三维表面模型也可以在任何切片上”切开”，并将适当的原始组织学图像叠加在卵裂平面上。图像堆栈也可以在任何任意planes.Conclusion切除：该模型是一个强大的教学工具，用于学习人体颞骨的复杂解剖结构，并为相关的二维形态看到的组织切片的三维解剖。该模型可以从伊顿-皮博迪实验室的网站下载，打包在一个跨平台的免费三维浏览器，它允许完全的旋转和透明度控制。
Objective:To develop a three-dimensional virtual model of a human temporal bone based on serial histologic sections.Background:The three-dimensional anatomy of the human temporal bone is complex, and learning it is a challenge for students in basic science and in clinical medicine.Methods:Every fifth histologic section from a normal 14-year-old male was digitized and imported into a general purpose three-dimensional rendering and analysis software package called Amira (version 3.1). The sections were aligned, and anatomic structures of interest were segmented.Results:The three-dimensional model is a surface rendering of these structures of interest, which currently includes the bone and air spaces of the temporal bone; the perilymph and endolymph spaces; the sensory epithelia of the cochlear and vestibular labyrinths; the ossicles and tympanic membrane; the middle ear muscles; the carotid artery; and the cochlear, vestibular, and facial nerves. For each structure, the surface transparency can be individually controlled, thereby revealing the three-dimensional relations between surface landmarks and underlying structures. The three-dimensional surface model can also be" sliced open" at any section and the appropriate raw histologic image superimposed on the cleavage plane. The image stack can also be resectioned in any arbitrary plane.Conclusion:This model is a powerful teaching tool for learning the complex anatomy of the human temporal bone and for relating the two-dimensional morphology seen in a histologic section to the three-dimensional anatomy. The model can be downloaded from the Eaton-Peabody Laboratory web site, packaged within a cross-platform freeware three-dimensional viewer, which allows full rotation and transparency control.
