ABSTRACT:
A solid state radiation sensor array panel comprising a thick deposited radiation detector layer capable of generating electron-hole pairs in response to being irradiated, and a matrix array of transistors comprising source and drain electrode elements, a charge transport layer, and a dielectric layer disposed over one surface of the detector layer. Means is provided for establishing an electric field across the detector layer, which field is collapsible to establish a higher field in irradiated areas so as to establish a current path, between the source and drain electrode elements, through pixel areas of the charge transport layer. The currents passing through pixel areas are passed to a readout circuit for processing the radiation image information.
