防散射滤线栅性能及应用研究

The characteristics and the application investigation of anti-scattered grids

介绍放射诊断中防散射滤线栅的一种最优化的设计方法，即合理选择滤线栅的保护层与间隔材料，合理地进行滤线栅参数与Ｘ线机管电压组合，以期在Ｘ线摄影中不仅得到高质量的影像，而且使患者接受低的射线剂量。

A method of designing excellent anti-scattered radiation grid used in diagnostic radiology is introduced.In the design,these factors were considered in order to obtain high image quality and low radiatson dose:the correct material used for grid protecting lay and interspace lay;the correct parameters(N,r.d) and the X-tube voltage.
