1. A system, comprising: an x-ray source, configured to generate high-energy x-ray photons; an x-ray detector comprising a converter and a scintillator, the x-ray detector being configured to receive the high-energy x-ray photons from the source, to convert the high-energy x-ray photons into a plurality of light photons; a plurality of image acquisition devices arranged in a two-dimensional array with overlapping fields of view, each image acquisition device of the plurality of image acquisition devices being configured to generate a plurality of x-ray images of a moving object crossing between the x-ray source and the x-ray detector at a high rate of speed from the plurality of light photons produced by the x-ray detector; a central control circuit configured to combine the plurality of x-ray images captured by the plurality of image acquisition devices into a set of combined x-ray images; a timing device disposed in the central control circuit and communicatively coupled to the x-ray source and the plurality of image acquisition devices, the timing device being configured to synchronize a timing of the generation of the high-energy x-ray photons in the x-ray source with the generation of x-ray images by the plurality of image acquisition devices; and a reflective surface positioned to reflect the plurality of light photons produced by the x-ray detector to a plurality of sensors included in the plurality of image acquisition devices.
