Described herein is a portable, self-contained, electronic radioscopic imaging system that utilizes a multiple camera imager and advanced processing techniques to image suspicious containers. An X-ray sensor or imager utilizes a scintillating screen that produces flashes of light when impinged by an X-ray in combination with at least one camera, or the like, to produce an integrated signal that represents the sum of a prescribed number of flashes of radiation that pass through the object in a given pixel area. A self-contained display and control unit utilizes digital signal processing in order to display to an operator the full dynamic range and resolution of an image-capturing novel sensor utilized within the imager.
