摘要
介绍了计算机射线照相技术(CR)和增感屏技术的原理。采用9 MeV直线加速器X射线源、iCR3600+系统和CR UR-1型IP板等,试验了透照不同厚度钢板时,增感屏对IP板成像的增感效果。得到了透照不同厚度钢板时灵敏度最高的增感屏厚度,以为工程应用提供参考。
This paper introduces the principle of the computer radiography technology and intensifying screen.Using 9MeV X-ray accelerator system,iCR3600＋and CR UR-1IP board,etc.,the transillumination of steel plate with different thicknesses shows the imaging sensitization effect of the intensifying screen to IP board.Corresponding thicknesses of intensifying screen resulting in the highest sensitivity for steel plate of various thicknesses were obtained,which might provide useful reference for engineering applications.
