Abstract
A method for inspecting cargo with is disclosed. The method includes scanning the cargo with a matrix including at least two rows of detectors, wherein each zone of the cargo irradiated by a first X ray pulse is irradiated by at least one second X ray pulse, and a radiation corresponding to the first X ray pulse is detected by a first row of the matrix, and a radiation corresponding to the at least one second pulse is detected by at least one second row of the matrix, generating a first image of the cargo and at least one second image of the cargo, determining, for each zone of the cargo irradiated, a local mutual parasitic displacement between the cargo and the matrix, determining a total mutual parasitic displacement, and generating a corrected image of the cargo without the mutual parasitic displacement.
