| abstract | Article inspection device, comprising: an x-ray machine; a collimation unit (4) to form x-rays generated by the x-ray machine obtaining a sector beam (5) in order to project an article; an array of transmission detectors (10) for detecting the x-rays that are transmitted through the article in order to form a two-dimensional image of the article; and at least one array of dispersion detectors (12, 13) comprising, each of them, a plurality of identical dispersion detector modules (Bxy, (xy)) arranged in an array of i rows and j columns, being a effective section of transmission of the article, transmitted by x-rays, divided into a plurality of identical subregions arranged in a matrix of i rows and j columns, in which the plurality of dispersion detector modules arranged in i rows and j columns corresponds to the plurality of subregions arranged in i rows and j columns, one by one, to detect annihilation photons by effect of producing pairs and scattering photons by Compton effect of the respective subregions produced by x-rays, characterized in that the inspection device of articles is configured to obtain atomic numbers of the respective subregions based on a relationship of annihilation photon count by the effect of producing pairs with respect to the count of scattering photons by the Compton effect, so that a three-dimensional image of the article is formed, in which "i" is a positive integer equal to or greater than 2, and "j" is a positive integer equal to or greater than 2, in which each dispersion detector module is designed and arranged so that only the scatter photons by Compton effect of the subregion corresponding to the dispersion detector module, can enter the dispersion detector module , each dispersion detector module comprising a collimator; and wherein, said at least one array of dispersion detectors (12, 13) further comprises two arrays of dispersion detectors comprised of: a first array of dispersion detectors (12) having a plurality of first detector modules of equal dispersion (Bxy) arranged in an array of i rows and j columns; and a second array of dispersion detectors (13) having a plurality of second equal dispersion detector modules (xy) arranged in an array of i rows and j columns; wherein, the article inspection device further comprises: a plurality of match counters corresponding to the plurality of subregions arranged in i rows and j columns, one by one, where, when one of the first dispersion detector modules and one of the second dispersion detector modules corresponding to the same sub-region receive "almost simultaneously" the photon of the same sub-region, the match counter corresponding to the same sub-region is increased by "1", so that the photon count of annihilation due to peer production effect; wherein the expression "almost simultaneously" means that the time difference between a time in which the first dispersion detector module receives the photon and a time in which the second dispersion detector module receives the photon is within a predetermined range ; and a plurality of first dispersion counters corresponding to the plurality of subregions arranged in i rows and j columns, one by one, where, when one of the first dispersion detecting modules corresponding to a subregion receives the photon of that subregion, the first scatter counter corresponding to the subregion is increased by "1", so that the scatter photon count by Compton effect is obtained. |
