Abstract: Computed radiography is a research hot in present NDT field. The effect of various parameters on the sensitivity was analyzed. Experiments were carried out to verify the effect of parameters on image quality, such as X-ray tube voltage, exposure, imaging plates type and scanning parameters. At last the problems needed for special concerning were concluded for CR technology.-
