The Key Technology Discussing of JB/T 4730.11 Digital Radiography Standard Setting

In order to popularize application of digital radiography technology in the special equipment field, and promote the special inspecting level in nondestructive testing industry, improve the efficiency of special equipment inspecting, and reduce the inspecting complexity for staff, and decrease environmental pollution. The advanced technology of digital radiography should be masted and the relevant testing standards should be established. Some key technologies of standards setting include: ① The components of digital radiography system in standards. ② The differences of image quality evaluation between digital radiography and film radiography. ③ The consistency and equivalence between digital radiography and film radiography. ④ other technologies should be concerned in digital radiography.
