摘要： An x-ray inspection system includes a vehicle, a mobile conveyance, and first and second x-ray scanning modules. The first module is transportable directly or indirectly, via a transport of the vehicle, to an inspection site, and it can irradiate a near side of an object to be inspected at the site with a first x-ray scanning beam. The second scanning module is transportable to the inspection site via a combination of the mobile conveyance and the vehicle, it the second module is movable and positioned at the inspection site, via the mobile conveyance, to irradiate a far side of the object with a second x-ray scanning beam. The vehicle and the mobile conveyance are configured to be mechanically coupled together during the transport and to be mechanically decoupled from each other at the inspection site. The system enables dual-sided x-ray backscatter inspection using a mobile platform.

摘要： This invention relates to a movable article inspection system and inspection method, wherein the inspection system comprises: a first automated guided vehicle, a radiation source and a detection mechanism; said radiation source and said detection mechanism are both mounted on said first automated guided vehicle, said first automated guided vehicle is able to move to a preset scanning inspection position, such that scanning inspection of said article to be scanned is effectuated by means of relative movement between an article to be scanned and the first automated guided vehicle. Such movable inspection system based on an automated guided vehicle is capable of making full use of an existing automated guided vehicle and its control system to make a movement path of the inspection system more flexible, and capable of effectuating centralized control and management of the inspection system, so that it can improve inspection efficiency, and save labor cost.

摘要： Radiation scanning systems providing multiple views of an object in different planes and a reconstruction algorithm for reconstructing quasi-three-dimensional images from a limited number of views. A system may include bend magnets to direct accelerated charged particles to multiple targets in different viewing locations. Another system collimates radiation generated by a plurality of radiation sources into multiple beams for scanning an object at multiple angles. The object may be a cargo container, for example. The reconstruction algorithm uses an optimization algorithm and imaging and feasibility models to reconstruct quasi-three-dimensional images from the limited number of views.

摘要： The present disclosure relates to detection systems and methods. One illustrative detection system may include a distributed radiation source having a plurality of radiation source focus points, which irradiate an object under detection, wherein the plurality of radiation source focus points are divided into a certain number of groups, and a primary collimator that limits rays of each of the radiation source focus points such that the rays emit into an XRD detection device. An XRD detection device may include a plurality of XRD detectors that are divided into the same number of groups as the radiation source focus points, wherein XRD detectors in a same group are arranged to be separated by XRD detectors in other groups, and rays of each of the radiation source focus points are received by XRD detectors having the same group number as the group number of the radiation source focus point.
