    摘要： 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.

    摘要： 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.

    摘要： A radiation imaging system comprising a radiation imaging apparatus in which pixels are arranged, a radiation source, a display unit, and a controller is provided. The controller causes, during radiation irradiation, the radiation imaging apparatus to repeat a generation operation of generating one image data by causing the pixels to perform an accumulating operation and a readout operation. When it is instructed to terminate the radiation irradiation, the controller causes the radiation source to stop the radiation irradiation in accordance with completion of the accumulating operation and the readout operation of the last row in the generation operation during which it was instructed to terminate the radiation irradiation, and causes the display unit to display an image based on last image data generated by the generation operation during which it was instructed to terminate the radiation irradiation.

    摘要： A system and method for identifying lithology based on images and XRF mineral inversion solving the problem that conventional lithology identification relies on manual work, which is time-consuming, subjective and can cause misjudgment. The identification system includes an autonomous vehicle; an X ray fluorescence spectrometer probe, and tests surrounding rock element information; image collection device; and vehicle-mounted processor. The processor inverts the received surrounding rock element information into mineral information based on a Barthes-Niggli standard mineral calculation method; and receive surrounding rock images and a corresponding inclination angle thereof, convert the surrounding rock images into image information in a one-dimensional vector format, splice the image and mineral information which is in a one-dimensional format, and distinguish the spliced information based on a preset neural network to identify rock lithology.

    摘要： A device and method in which neutral atoms or molecules are used to observe surfaces of samples and capable in particular of producing information from inhomogeneous samples where the forces and interactions are of strength characterized by moderate temperatures in the range of 100*K to 500*K. Molecules evaporating from the surface of a sample are shown selected by a pin-hole and detected and converted to an ion current by a surface ionizing detector. With relative scanning movement of components of the system, the ion current is monitored and recorded, indicating the spatial variation in evaporation of the molecules from the sample.
