摘要
建立了基于宏孔硅的X射线CsI(Tl)闪烁屏模型,模拟分析了X射线能量对X射线CsI(Tl)闪烁屏光输出的影响。制备了周期为10μm、方孔边长为8μm的X射线闪烁屏,搭建了X射线成像装置,测量了不同X射线源管电压的X射线成像图,采用Matlab软件分析了X射线闪烁屏的光输出情况。研究结果表明,闪烁屏厚度越大,闪烁屏平均灰度值越大,与模拟结果一致。
A model of Xray CsI(Tl)scintillation screen based on the macroporous silicon is established,and the influence of Xray energy on the Xray CsI(Tl)scintillation screen’s light output is simulated and analyzed.An Xray scintillation screen with a period of 10μm and a side length of 8μm was prepared,and an Xray imaging device was constructed.The Xray images of different Xray sourcetube voltages were measured.The light output of the Xray scintillation screen was analyzed using MATLAB software.The results show that an increase in the thickness of the scintillation screen increases the average gray value of the scintillation screen,which is consistent with the simulation results.
