  • Binderless storage phosphor screen on a dedicated support
    Patent number: 7091501
    Abstract: A binderless stimulable phosphor screen comprises a vapor deposited storage phosphor layer on a support and a protective layer wherein the vapor deposited phosphor is needle-shaped with voids between the needles, wherein the voids are partially filled with a polymeric compound.
    Type: Grant

    Inventors: Ludo Joly, Rudi Van den Bergh, Paul Leblans
  • Radiation image storage panel having a particular layer arrangement
    Patent number: 6927404
    Abstract: A radiation image storage panel. The panel has a supported layer of storage phosphor particles dispersed in a binding medium, and adjacent thereto, between the layer and a support having reflective properties, a layer arrangement of intermediate layers inbetween the layer and the support. The layer arrangement consists of an antihalation undercoat layer containing one or more dye(s), the layer being situated more close to the support, and an adhesion improving layer situated more close to the layer of storage phosphor particles, and wherein the adhesion improving layer is hardened to a lesser extent than the antihalation undercoat layer.

  • Phosphor panel with a protective layer
    Patent number: 6822243
    Abstract: A phosphor panel with a protective coating divided in at least two layers: a layer A, being closest to said phosphor layer and a layer B farther away from said phosphor layer wherein the layer A has a lower water vapor permeability coefficient than the layer B. Layer A has a water vapor permeability coefficient, P, so that 0 ≤ P ≤ 1 × 10 - 11 ⁢ cm 3 ⁡ ( STP ) · cm cm 2 · s · P ⁢   ⁢ a .
