    • Disclosed in an x-ray imaging device, which uses a Talbot-Lau interferometer, eliminates the effects on image quality of a reconstructed image that arises in such cases as when the direction of a multi-slit or each lattice slit is altered and imaging is performed, and provides reconstructed images favorable for diagnosis. When a plurality of moire images imaged with an imaging subject loaded onto a imaging subject stand (13) and a plurality of moire images imaged without the imaging subject are input, a control unit (51) of a controller (5) corrects signal value differences arising from variations in x-ray strength during imaging respectively between the plurality of moire images with the imaging subject and between the plurality of moire images without the imaging subject, and respectively creates a reconstructed image with the imaging subject and a reconstructed image without the imaging subject. Then, the control unit (51) creates a reconstructed image of the imaging subject for diagnosis by correcting, on the basis of the reconstructed image without the imaging subject, image unevenness in the reconstructed image with the imaging subject caused by heterogeneity in light distribution caused by the angle of rotation of the multi-slit.

    • A non-intrusive inspection system, including apparatuses and methods, for non-intrusively inspecting containers such as, without limitation, those employed to transport items in international commerce. The non-intrusive inspection system is configured to generate and scan a container with multiple bremsstrahlung, or x-ray, beams having multiple spectra and directed at the container in multiple directions and planes separated by one or more angle(s). Using data collected from such scanning, software of the non-intrusive inspection system generates three-dimensional images of the items present in a container, calculates the volumes and densities of such items, computes effective “Z” numbers, and distinguishes between multiple materials, or elements, of such items. By employing multiple bremsstrahlung beams directed upon a container in multiple planes, the non-intrusive inspection system reduces the number of orientations and geometries of items within a container that might otherwise be employed to avoid the detection of harmful materials being transported within a container.
