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. A preferred embodiment of the detector plate includes an electrically insulative barrier of silicone based Sylgard in the margin around the periphery of the first conductive layer in the form of a "dam" to further prevent arcing and resulting detector plate failure. It is also preferable to include a linear contact on the first conductive layer adapted to connect a high voltage electrode of a power supply to the first conductive layer. The first conductive layer is more stable with the linear contact, as compared to a conventional circular contact.
