The quantitative measurement of the three-dimensional (3-D) anatomy of the ear is of great importance in the making of teaching models and the design of mathematical models of parts of the ear, and also for the interpretation and presentation of experimental results. This article describes how we used virtual sections from a commercial high-resolution X-ray computed tomography (CT) scanner to make realistic 3-D anatomical models for various applications in our middle-ear research. The important problem of registration of the 3-D model within the experimental reference frame is discussed. The commercial X-ray CT apparatus is also compared with X-ray CT using synchrotron radiation, with magnetic resonance microscopy, with fluorescence optical sectioning, and with physical (histological) serial sections.
耳朵三维(3-D)解剖结构的定量测量对于制作教学模型、设计耳部各部分的数学模型以及解释和展示实验结果都非常重要。本文描述了我们如何使用商业高分辨率X射线计算机断层扫描(CT)扫描仪的虚拟切片,为中耳研究中的各种应用制作逼真的3-D解剖模型。讨论了3-D模型在实验参考框架内配准的重要问题。还将商业X射线CT设备与使用同步辐射的X射线CT、磁共振显微镜、荧光光学切片以及物理(组织学)连续切片进行了比较。
