A photo-optical imaging system suitable for use in an electronradiography system which produces an electrostatic charge image at an electrode. An electrode having a photoconductor layer and a transparent electrical conducting layer, with the charge image at the photoconductor layer. A light beam and various arrangements for scanning the beam over the photoconductor layer through the transparent layer for selectively transferring charge to the electrically conducting layer through the photoconductor layer as portions of the photoconductor layer are illuminated by the beam, and a data storage unit for receiving and storing data corresponding to the magnitude of charge at the photoconductor layer.

Direct charge readout electron-radiography chamber

An electronradiography imaging chamber providing a real time visual image. An electronradiography imaging chamber with electrophoretic particles in the electrode gap, with the particles being selectively moved to a transparent electrode as a result of the electrostatic charge image formed by absorbtion of incoming X-ray radiation in the gap. A dark field illumination viewing configuration with the deposited particles providing light scattering giving a visual image with low radiation dosage. An imaging chamber which can be cyclically operated at a relatively high repetition rate, typically 10 to 20 images per second, thereby providing real time viewing of the object.

X-ray system with electrophoretic imaging

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.
