用生物塑化技术制作１．２ｍｍ厚的薄层断面标本，用图像工作站为主机，组成三维重建系统，对包含有颅骨、脑干、垂体、血管、神经等多种结构的人体蝶鞍、斜坡区进行了三维重建观测。重建的所有结构均可以单独显示、任意搭配显示或总体显示；所有结构均可在三维空间绕任意轴旋转任意角度，或以不同速度连续旋转。三维显示一幅包含５０个断面的图像，或转动一幅已重建的图像，仅用１．５ｓ。对所有结构在任意方向上的径线和角度均可适时测量。由于采用了先进的断面标本制作技术和高性能的图像工作站，在编程时将极角排序连结算法和重心位置协调算法相结合，较之以往的三维重建研究，原始数据采集量大，采用了准确的图像输入方法，图像显示效果好，重建速度快，并较好地解决了计算机三维重建中准确定位的问题。
Biomedical plastic technology to produce 1.2mm thick thin section of the specimen, the image workstation as the host to form a three-dimensional reconstruction system, including the skull, brain stem, pituitary, blood vessels, nerves and other structures of human sella, slope District conducted a three-dimensional reconstruction observation. All structures reconstructed can be individually displayed, collocated or displayed as a whole; all structures can be rotated at any angle around any axis in 3D or continuously at different speeds. Three-dimensionally display an image of 50 sections or rotate a reconstructed image in just 1.5 seconds. For all structures in any direction of the diameter and angle can be timely measurement. Due to the advanced cross-section specimen making technology and high-performance image workstation, the polar angle alignment algorithm and the center-of-gravity position coordination algorithm are combined in the programming. Compared with the previous 3D reconstruction research, the original data acquisition volume is large and the accuracy Image input method, the image display effect is good, the reconstruction speed, and better solve the problem of accurate positioning in the computer three-dimensional reconstruction.
