Abstract: The basic principles and characters of portable DR and CR imaging technique were introduced. Through the real weld testing, the imaging characters by these two kind of imaging technique, and the imaging effect by using continuous or pulsed ray source were compared. It provided a certain help for using the portable DR and CR.
