X-ray image intensifier having columnar crystals having a cross section decrease as it goes towards the edge |
摘要 |
An X-ray image intensifier includes an input screen for converting incident X-ray into photoelectrons. The input screen has a substrate, a phosphor layer having a layer number of columnar crystals of a phosphor formed with gaps therebetween on the substrate, and a photoelectric layer directly or indirectly provided on the phosphor layer. The columnar crystals at a peripheral edge portion of the input screen are thinner than the columnar crystals at a central portion of the input screen.
