It is generally believed that properly constructed high ratio grids are very efficient in removing radiographic scatter. The authors show that grids inherently transmit substantial amounts of contrast-degrading scatter and suggest a better method of eliminating it. A system of moving paired slits produces radiographic images with higher contrast than do grids at the same tube voltage. The diagnostic implications are discussed.
一般认为，结构合理的高比值滤线栅在去除射线照相散射方面非常有效。作者表明，滤线栅本身会传输大量降低对比度的散射，并提出了一种更好的消除散射的方法。移动双缝系统在相同管电压下产生的射线照相图像比滤线栅具有更高的对比度。文中讨论了其诊断意义。
