  • Patent number: 9739896
    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.

  • Patent number: 9079217
    Abstract: There is described a method of manufacturing a digital radiography panel. The method includes providing a scintillator screen and spray coating an acrylic adhesive composition on the scintillator screen. A flat panel detector and the scintillator screen with acrylic adhesive composition are compressed together at a force of about 5 psi to about 15 psi, at an atmospheric pressure of about 0.3 Torr to about 100.0 Torr for a time sufficient to affix the flat panel detector to the scintillator screen to form the digital radiography panel.
