降低GE ADVANTX系列X线机图像噪声的研究

THE RESEARCH OF REDUCING XRAY IMAGE NOISE OF GE ADVANTX MACHINE

噪声在Ｘ线设备图像系统中难以排除。本文从几个方面讨论了降低ＡＤＶＡＮＴＸ系列Ｘ线机图像噪声方法。从机房布局、电缆走行、电缆沟与地线的制作到设备各部件之间的连接都是降噪的系统工程。实践证明，降噪的有效方法是屏蔽由设备自身产生的和外界引入的电磁干扰。视频电缆与其它电缆置于各自电缆沟内。

It is very difficult to eliminate the noise in the Xray image.Writer discusses in this paper that how to reduce noise in Xray image at the ADVANTX Xray equipment.The work of reducing noise is a system engineering which includes scientific layout machine room of ADVANTX system,interconnection cables,making cable duct and earthling assembly,and so on.Practical results are presented that those mentioned works be sure to lead to reduce noise.The emphasis is that effective methods of decreasing noise of Xray image are shield of electromagnetic interference produced from Xray equipment and surrounding.Video cable and other cables should be individually put in their duct.
