  • Panel type radiation image intensifier
    Patent number: 4855589
    Abstract: A multistage, proximity type, radiation image intensifier tube having improved performance characteristics and more rugged construction is provided. A scintillator assembly is comprised of a first ceramic, cellular substrate defining an array of hexagonally shaped cells. The cell walls taper to an edge and are coated with a conductive material such as aluminum. The cells are filled with a scintillation material such as cesium iodide. A first flat photocathode is provided adjacent the first substrate. An intermediate assembly spaced from the scintillator assembly is provided comprised of a second ceramic, cellular substrate similar to the first. The cell walls are coated with a conductive material such as aluminum. A support layer is mounted to the substrate on an end opposite the scintillator assembly. A first flat phosphor display screen is mounted to the support layer on a side internal the second substrate. A second photocathode is provided adjacent the second substrate.
    Type: Grant

    Date of Patent: August 8, 1989
    Assignee: Picker International, Inc.
    Inventors: Richard S. Enck, F. Dan Meadows
