| Abstract: | In X ray digital radiographic system, there are many kinds of noises which originate from different imaging elements, such as CCD camera, scintilator photoconvertor, X ray scatter, control circuit and so on. These kinds of noises have serious influence on imaging quality. The origins and characteristics of the noises in the system are studied by means of experiments, and the method of noise depression is presented. It is shown that the results of noise depression are effective. |
