  • Method of identifying materials from multi-energy X-rays
    Patent number: 9311277
    Abstract: A calibration method for a device for identifying materials using X-rays, including: a) determining at least one calibration material and, for each calibration material, at least one calibration thickness of this material, b) measuring, for each of the calibration materials and for each of the selected calibration thicknesses, attenuation or transmission coefficients for X radiation, c) calculating statistical parameters from the coefficients, d) determining or calculating, for each calibration material and for each calibration thickness, a presence probability distribution law, as a function of the statistical parameters.
    Type: Grant

  • Method for reconstructing a radiographic image by combining elemental images
    Publication number: 20060251208
    Abstract: In a radiographic method where an object (2) is studied in several steps by a radiation (4) occupying various positions (4i, 4j) just as the associated network of detectors (3i, 3j), the combination of elementary vignettes into an overall image without junction defects is resolved by a discretisation of the object (2) into volumes and a calculation of the attenuation in each volume (voxel) (8) to obtain images of the object at different reconstruction heights; then said images are combined with each other to obtain a final, more exact image.
