In one example, there is provided a matrix of detectors configured to be used in a system for inspecting cargo using inspection radiation. The matrix includes a plurality of columns of detector modules, the detector modules of each column extending along a substantially longitudinal direction, each detector module including a surface configured to receive the inspection radiation, and the plurality of columns of detector modules being adjacent to each other in a lateral direction substantially perpendicular to the longitudinal direction and substantially parallel to the surfaces of the detector modules, wherein the plurality of columns of detector modules includes at least two columns of detector modules being offset with respect to each other in an in-depth direction substantially perpendicular to both the lateral direction and the longitudinal direction.

A method for determining a flux of inspection radiation is provided, wherein the inspection radiation is emitted by a radiation source and transmitted through cargo, and wherein the flux of inspection radiation is incident on at least one array of detector cells. The detector cells are configured in a first plurality L forming rows of the array, each row of detector cells extending along a direction parallel to a depth direction of the array, the detector cells being further configured in a second plurality λ forming columns of the array, each column of detector cells extending along a direction parallel to a longitudinal direction of the array. The method includes obtaining signal data associated with each detector cell of the array, and determining the flux of the inspection radiation incident on row i, for each row i such as 1≤i≤L, based on the signal data for each detector cell.

The method includes obtaining data associated with a scanning of at least one part of the cargo with a current frequency f, wherein the scanning includes displacing the cargo and the system with a relative scanning displacement; determining a pace δ, at a predetermined instant t; and determining whether the determined pace δ is reliable. If the pace is reliable, the current frequency is updated.

Pulse frequency adjustment

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.

Two-dimensional detector of ionizing radiation and process for manufacturing this detector This detector comprises sheets () emitting particles by interaction with ionizing radiation, semiconducting layers () that alternate with the sheets and can be ionized by the particles, and groups of conducting tracks () in contact with the layers. Means () of creating an electric field are used to collect charge carriers generated in the layers due to interaction with particles, through the tracks. For example, the layer and the corresponding tracks are formed on each sheet and the sheets are then assembled together. For example, the invention is applicable to radiography and can achieve good X-ray detection efficiency and high spatial resolution at the same time.

This is a method of generating a plurality of images of a substrate from radioactive radiation coming from a plurality of radioactive tracers contained in the substrate. To this end, data representing the different detection signals generated by a detector are memorised, individually for each radioactive emission detected during a certain observation period, then statistical processing of these data is carried out in such a way as to estimate the images of the different tracers which correspond best to the set of memorised data.
