ABSTRACT:
An electronradiography imaging chamber providing a visual image at the chamber suitable for direct viewing and/or copying. An imaging chamber with a first electrode on the x-ray source side, an x-ray absorber in a gap between the first electrode and an anisotropic plate, and a liquid crystal material in a second gap between the plate and a second transparent electrode, with incoming x-radiation providing a charge image on the plate at the absorber gap, with the plate transferring the charge image to the liquid crystal side and modulating the liquid crystal material to produce a visual image of the charge image, which visual image is viewable through the second electrode.
