| Abstract: | The nondestructive testing radiography system based on amorphous silicon flat-panel detector（FPD） is discussed in detail. The imaging process and performance of PaxScan FPD is introduced, the main parts of the designed system and their main functions are given, and the reasons which result in image degraded are analyzed. Then the calibration was made according to the facors which result in image degrading of detector. Experimental result show that the imaging quality can reach industrial superlative degree of level B. |
