  • Publication number: 20120312998
    Abstract: A radiation image conversion panel which can improve its optical output and resolution is provided. A radiation image conversion panel 1 comprises a FOP 2, a heat-resistant resin layer 3 formed on a main face 2a of the FOP 2, and a scintillator 4 formed by vapor deposition on a main face 3a of the heat-resistant layer 3 on a side opposite from the FOP 2 and made of a columnar crystal. In this radiation image conversion panel 1, the main face 3a of the heat-resistant resin layer 3 has a surface energy of at least 20 [mN/m] but less than 35 [mN/m]. This can make the crystallinity of the root part of the scintillator 4 favorable, so as to inhibit the root part of the scintillator 4 from becoming harder to transmit and easier to scatter the output light.

  • Publication number: 20120025102
    Abstract: In a radiation image conversion panel (10), a radiation conversion layer (2) for converting an incident radiation into light is formed on a substrate (1). The radiation conversion layer (2) has a reflective layer (3), on a side opposite from a light exit surface (2a) for emitting the light, for reflecting the light to the exit surface (2a) side, while the reflective layer (3) has a helical structure comprising helically stacked phosphor crystals. Thus constructed radiation image conversion panel (10) can enhance the reflectance without forming a reflective layer made of a thin metal film or the like and exhibit a reflectance higher than that in the case where the reflective layer is formed by spherical crystal particles.
