  • 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.
