Patent number: 9739896Abstract: 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.Type: GrantFiled: November 17, 2016Date of Patent: August 22, 2017Assignee: Carestream Health, Inc.Inventors: Seshadri Jagannathan, Timothy J. Tredwell, Charles M. Rankin, David Gruszczynski, Daniel M. Leusch

Patent number: 9079217Abstract: 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.Type: GrantFiled: February 25, 2013Date of Patent: July 14, 2015Assignee: Carestream Health, Inc.Inventors: Seshadri Jagannathan, Timothy J. Tredwell, Eric L. Dillenbeck, David Gruszczynski, Daniel M. Leusch, Charles M. Rankin, Bradley S. Jadrich, Brian P. Aylward, Kevin L. Bishop
