The Studying Of Collection Of X-Ray Image Intensifier At Low-Noise

The article mainly describes some researches on X-ray imaging systerm and its noise. As we all know, with the using of X-ray imaging systerm more and more and the progress of science and manmufacture,the mistakes in manufacturing which affect the image of X-ray imaging systerm less and less,so noises becomes the most important reason in the all reasons which affect the image quality of X-ray imaging systerm.The research began with the studying of the composition of the X-ray imaging systerm and it's principle,we found the noises come frome two parts:one is X-ray image intensifier ,another is CCD systerm. Analysis the work condition and the principle of the last two parts,we found improve the condition of the X-ray image intensifier manufacture and change it's work condition can lower it's noises,lower the temperature of the CCD systerm or extension of it's work time can lower it's noises,we can use the experiments to testfy these theorises.This paper is useful for the X-ray imaging systerm to improve it's image quality and promoted it's application.
