新一代X射线检测器在射线实时成像检测中的应用

The applicatiaon on real-time radioscopic inspection with x-ray sensitive detectors of a new generation

介绍非晶硅(a-Si)平板检测器的技术特性,及其取代常用的图像增强器在工业射线实时成像检测中的应用——焊缝和铸件检验。实验结果证明:选用适当型号的a-Si平板检测器,可获得优于图像增强器的像质计(IQI)灵敏度和空阃分辨力。这是工业数字射线照相技术实用化的又一新突破。

The technical properties of a new generation of X-ray sensitive detectors-amorphous silicon（a-Si）flatpanel detectors are introduced，The new detectors can be in lieu of the usualimage intensifier in X-ray real-time radioscopie（RTR）system for inspecting welds or castings，Experimental results have shown that a suitable a-Si detector can achieve better IQI sensitivity and space resolution than an image intensifier，This is anothernew new breakthrough bring the industrial digital radiography into the practical domain。
