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.

Portable system and method for non-intrusive radioscopic imaging

Digital pixel data is obtained from radiographic imaging of one or more objects, and corresponds to an imaged area containing a feature to be measured. A data profile for a region around the measured feature is created from the digital pixel data. A reference profile is then created from the data profile. The reference profile represents an expected data profile for a reference condition of the objects, and accounts for the point spread function of the imager. The difference between the data profile and the reference profile is calculated. Based on that difference, the degree by which the actual condition of the objects varies from the reference condition is determined. The calculated difference can be compared to a lookup table mapping previously calculated differences to degrees of variation from the reference condition. The calculated difference can also be used as an input to an experimentally derived formula.
