“…The shield of CCD should be strengthened in order to reduce the effect of X-ray to CCD when we get the X-ray image. As we known, the nonlinear filters are often applied in noise removing, such as median filter which provides with cleaning dust and protecting image details [9] . The output of recursive filtering which is also called feedback filtering depends on not only the input and response function, but also the output.…”

The influence of X-ray on imaging device such as CCD and the interaction effect between X-ray and imaging device are analyzed. It is indicated that the noise from X-ray radiations may be regarded as positive impulse which randomly distributes in space though the experiments. With the integration time and radiation energy increasing, the quantity and amplitude of the noise are enhanced as well. An adaptive diamond filter is presented for removing this kind of noise and compared with the recursive and non-recursive median filter through computer simulations and actual applications. It is shown that the filter presented is of the abilities that may remove impulse noise and protect edges and details more effectively.Keywords-interaction effect between X-ray and matter; imaging device noise; noise removing; adaptive diamond filter
