Abstract
The structure and theory of filmless radiography were introduced. And the usage and prospects of the techniques were analyzed, including the fluoroscope, image intensifier, computed radiography and digital radiography. The highlights of the nondestructive testing(NDT) market would be the digital radiography equipments. The developments of the technique would give birth to a real radiography revolution in the fields of NDT.
