Adhesive layer for digital detectors

摘要

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.
