Despite development of computer-assisted neurosurgical navigation, learning by dissecting anatomic specimens is still important.
We describe the processes from preparation of specimens for cranial dissection to documentation of three-dimensional (3-D) stereoscopic pictures, particularly focusing on the latter, which has been initiated in the Microneuroanatomy Laboratory, Department of Neurological Surgery, University of Florida.
Preparation consists of irrigation of the major vessels and injection of colored silicone. The 3-D documentation, obtaining two pictures corresponding to each eye's view, is obtained by the shoot-shift-shoot method using a single camera mounted on a slide bar. The key of this method is correct shifting of the camera without alignment error to get exact 3-D effects. Observation of 3-D image can be made with free viewing, a 3-D viewer, or projection. Tips concerning all of the processes involved are described.
The presented method of dissection and obtaining 3-D images is beneficial for accomplishing studies of anatomy and for providing teaching method.
尽管计算机辅助神经外科导航技术有所发展，但通过解剖标本进行学习仍然很重要。
我们描述了从准备颅骨解剖标本到记录三维（3-D）立体图像的过程，尤其着重于后者，这一过程已在佛罗里达大学神经外科系的显微神经解剖实验室开展。
准备工作包括冲洗主要血管并注入彩色硅胶。三维记录是通过使用安装在滑杆上的单个相机，采用拍摄-移动-拍摄方法获取与每只眼睛视角相对应的两张图片。该方法的关键在于相机的正确移动且无对准误差，以获得精确的三维效果。三维图像可通过自由观看、三维观察器或投影进行观察。文中描述了有关所有相关过程的技巧。
所介绍的解剖及获取三维图像的方法有助于完成解剖学研究并提供教学方法。
