Abstract Considering to the radiation image system charactertics and the existing problems of X-ray Compton back-scattering image, such as noise, background uniformity and contrast, a new hybrid filter is designed which is used to improve the image quality. After filtered, the X-ray back-scattering image with clear levels, distinct outline, uniform background will be displayed on the screen.
