Thales650HD-E平板探测器X射线成像系统设计

X-Ray Imaging system for Thales650HD-E flat panel detector

本文以泰雷兹(Thales)650HD-E平板探测器作为研究对象,根据工程需求用VS2010开发了一套X射线成像系统。采用多线程编程实现实时采集和图像显示功能。用多帧叠加消除采集图像的加性噪声。由于多帧叠加后图像边缘、轮廓变模糊,再将图像进行直方图均衡化然后与原图像进行叠加。通过实验及现场测试验证图像显示效果良好,实时性、稳定性满足工程需求。

In this paper, using Thales650HD-E flat panel detector as the research object,developed a set of X-Ray imaging system withVS2010 according to the requirement of the project. Using multi-thread programming achieves the functions of real-time image acquisitionand display. But the border and contour of the image appear blurred, so the method of histogram equalization to process the image then fusethe image and the original image. Through the experiment and field tests, the system verify that the quality of image display , real-time and stabilitycan meet the demand of engineering .
