    Abstract: Described is a scintillator screen that includes a supporting layer having a phosphor dispersed in a polymeric binder disposed on the supporting layer and a barrier layer disposed on the polymeric binder. The barrier layer includes a non-moisture absorbing polymer selected from the group consisting of polyethylene terephthalate, cellulose diacetate, ethylene vinyl acetate and polyvinyl butyraldehyde. The barrier layer has a thickness of less than 1 micron. An antistatic layer is disposed on the barrier layer. The antistatic layer includes poly(3,4-ethylenedixythiophene)-poly(styrene sulfonate) (PEDOT/PSS) dispersed in a polymer selected from the group consisting of a polyester and a polyurethane. The antistatic layer has a transparency of greater than 95 percent at a wavelength of from about 400 nm to 600 nm.

    Abstract: There is described a digital radiography panel that includes a scintillator screen, an adhesive layer and a flat panel detector. The scintillator screen includes a supporting layer; a phosphor dispersed in a polymeric binder disposed on the supporting layer and an antistatic layer disposed on the polymeric binder, wherein the antistatic layer has a transparency of greater than 95 percent at a wavelength of from about 400 nm to 600 nm and a surface resistivity of less than 105 ohms per square. The adhesive layer is disposed on the scintillator screen and includes a material selected from the group consisting of acrylic polymers and urethane polymers. The adhesive layer has a thickness of from about 5 μm to about 15 μm. The adhesive layer has a transmittance of greater than 95 percent at a wavelength of from about 400 nm to 600 nm. The flat panel detector is disposed on the adhesive layer.

    Abstract: Described is a scintillator screen including a plurality of filaments. Each of the plurality of filaments includes scintillating particles dispersed within a thermoplastic polymer. The thermoplastic polymer includes an elastic additive. The scintillating particles are from about 10 volume percent to about 60 volume percent of each of the plurality of filaments. Each of the plurality of filaments has a refractive index of greater than or equal to 1.5. The plurality of filaments are substantially parallel to each other and are at a volume packing of from about 60 percent to about 90 percent.
