  • Detector plate for use in imaging systems
    Patent number: 5637882
    Abstract: A detector plate for use in a radiation imaging system includes a first conductive layer, a dielectric layer, a photoconductive layer and a second conductive layer, arranged as a stack in that order. The first conductive layer and the dielectric layer are substantially transparent to radiation energy so as to allow the energy to pass therethrough to be received by the photoconductive layer. The first conductive layer has a periphery defined by a first edge and the dielectric layer has a periphery defined by a second edge, wherein the first edge is offset inward of the second edge defining a margin between the first and second edges. In use, this margin helps inhibit electrical arcing from the first conductive layer to the second conductive layer when a high voltage is applied between these two layers.
