Abstract: The problems in the present RTR(X ray Real time Radiography)system were discussed. The main reasons decreasing the measurement accuracy of RTR system were the low image resolution of high speed motion analyzer and the system error caused by the X ray system.Several available measures to improve the measurement accuracy of RTR system are summarized.These measures included the improvement of the stabilization property of voltage transformer,the enhancement of design level of test motor,the increase of the stiffness of test stand and the application of image processing techniques.These measures are used in the study of motion pattern of particles in SRM chamber and the measurement accuracy is improved obviously.
