一种用于X线数字直接成像系统的立体图象显示和观察装置

A stereo-image display and observation by switching gogg les on direct digital X-ray imaging device

本文详细地介绍了一种基于ＰＣ机的立体图象显示和观察装置。该装置利用ＴＶＧＡ－８９００显示卡的帧同步信号，通过特殊的软件交替切换左右两幅图象并控制液晶（ＬＣＤ）开关眼镜在ＰＣ机监视器上实现立体图象显示和观察的。它具有分辨率高，实时性好，操作简单等特点，并能根据观察者的需要随意改变物体的前后位置。该装置在医学图象诊断和工业无损探伤等领域具有较大的应用价值。

This paper introduces a kind of PC-based device used for stereo image display by switching goggles. This device can achieve stereo image display and be observed on the monitor of PC computer by a special software which changes left and right images alternatively and using the frame synchronous signal of TVGA-8900 display card controls the switching of a pair of LCD goggles. It has some features of high resolution, real-time and can change the orientation of object freely to meet the observer's need. This device is of great value in the fields of medical image diagnosis and industry non-destructive flaw detection.
