Abstract: The present invention discloses an ionizing radiation sensitive multi-layer structure having a charge accepting outer surface and comprising a conductive layer, said ionizing radiation sensitive multi-layer structure being operative such that imagewise ionizing radiation impinging on said ionizing radiation sensitive multi-layer structure causes a charge distribution, representing said imagewise ionizing radiation, to be formed in said conductive layer; and readout electronics coupled to said conductive layer to detect the charge distribution formed in said conductive layer.
