X线成像系统视频图像自动亮度控制问题分析

Analysis of the Automatic Brightness Controlling for X-Ray Imaging Systems

针对采用CCD摄像单元的影像增强器的视频自动亮度控制问题,分析了X线成像系统图像亮度控制相关过程以及亮度控制回路的结构和原理,介绍了典型设备的一种计算机亮度智能控制软件的设计思想和相关技术方法。

In this paper, the question about automatic brightness control for x-ray imaging systems based on CCD camera is discussed, and the structure and principle of an auto brightness control loop are analyzed along with the working procedure of the x-ray imaging system. A kind of digital brightness controller about a typical device and the designing idea of the computer brightness intelligent control software is introduced.
