Abstract: The characteristics of related qulity controlling parameters used in real-time X-ray imaging technique and computer image processing technique were discussed. Agreat deal of process trials and images aquisition were proceeded which taking the titanium alloy cylinder as the example. Testing results showed that the contrast and sensitivity of the image getting by X-ray real-time imaging technique was as good as X radiography testing technique. Defect detection rate was satisfied also. The best testing process parameters were got through those trials and the universal property of the max amplifying ratio was proved also.
