| 摘 要： | 感绿胶片／稀土增感屏系统可大大降低射线剂量。这主要是由于稀土增感屏比钨酸钙增感屏有较高的Ｘ线吸收效率及转换为可见光的效率。感绿的屏／片体系显示了细微的影像颗粒，具有较高的解像力。这主要是由于感绿片采用了Ｔ颗粒技术及抗交迭效应技术，提高了乳剂对荧光的吸收，同时防止交迭光的散射危害。

| Abstract: | Green sensitive film/Rare earth intensifying screens systems greatly reduce radiation dosages.This is the result of Rare earth intensifying screen,which absorbs and converts more x radiation to visible light than screen made with calcium tungstate.Green sensitive S/F systems offers fine grain images with high resolution.This is the result of T grain technology and anticross over technology which can greatly increase the efficiency of fluorescent light absorption and diminish scattering of cross over light. |
