Radiographic flat panel detector having a ferromagnetic layer and the method of production thereof
A radiographic flat panel detector includes a layer configuration in the order given: a) a radiation transparent substrate; and b) a scintillator layer applied by vapor deposition on the radiation transparent substrate; and c) an imaging array between the scintillator layer and a second substrate, characterized in that the radiation transparent substrate has on a side a layer including magnetisable particles and a method for producing the radiographic flat panel detector.
1. A method for producing a radiographic flat panel detector comprising the steps of:
providing a radiation transparent substrate with a layer including magnetizable particles;
contacting the radiation transparent substrate including the layer including magnetizable particles with a surface of a substrate supporting body positioned between one or more magnets and the radiation transparent substrate;
applying a scintillator layer on the radiation transparent substrate by vapour deposition while the radiation transparent substrate is fixed by magnetic forces to the substrate supporting body; and
bonding a surface of the scintillator layer that is not in contact with the radiation transparent layer to an imaging array that is provided on a second substrate.
2. The method for producing a radiographic flat panel detector according to claim 1 , wherein the layer including magnetizable particles is coated from a dispersion including magnetizable particles and a binder.
3. The method for producing a radiographic flat panel detector according to claim 1 , wherein, prior to the step of contacting:
applying a light reflecting layer onto a side of the radiation transparent substrate.
4. The method for producing a radiographic flat panel detector according to claim 2 , wherein, prior to the step of contacting:
applying a light reflecting layer onto a side of the radiation transparent substrate.
5. The method for producing a radiographic flat panel detector according to claim 1 , wherein, prior to the step of contacting:
applying an adhesion promoting layer onto a side of the radiation transparent substrate.
6. The method for producing a radiographic flat panel detector according to claim 1 , wherein the step of bonding is performed by melting a hot melt resin layer between the scintillator layer and the imaging array.
