散射射线对照相系统反差灵敏度的影响

Influence of Scattered Radiation on Contrast Sensitivity in Radiography

本文叙述了散射辐射对射线照相系统反差灵敏度的影响，计算了几种能量γ射线在铁板中的积累因子，讨论了几种减少散射影响的方法。

This paper describes the influence of scattered radiation on contrast sensitivity in radiography. The curves of buildup factors for several γ ray energies in steel plate are calculated and methods of scatter reduction are discussed.(
