Abstract: An imaging system for inspecting multiple objects includes an x-ray source having a beam width greater than or equal to a threshold beam size. The multiple objects is irradiated by the x-ray source in respective controlled inspection positions. A detection mechanism is adapted to acquire respective images of the multiple objects in the respective controlled inspection positions. The detection mechanism includes one or more detectors arranged circumferentially around a central axis. At least one positioning mechanism is adapted to move the multiple objects into and out of the respective controlled inspection positions.

Abstract: In a method of making pixelated scintillators, a block of an amorphous scintillator material is divided into plural sections. The plural sections of the block are rejoined with plural first reflective septa to form an assembly. In the assembly, each of the plural first reflective septa separates two adjacent sections of the block. The assembly is then divided into plural sections in a way such that each of the plural sections of the block is divided into plural pixels. The plural sections of the assembly are rejoined with plural second reflective septa. Each of the plural second reflective septa separates two adjacent sections of the assembly, forming an array comprising plural rows and columns of pixels of the amorphous scintillator material. In the array, each pixel is separated from adjacent pixels by a portion of at least one of the plural first reflective septa and at least one of the second reflective septa.

Abstract: A system operable for detecting radiation to scan an object includes scintillators that have respective lengths that are greater than their respective widths and an imager that has a planar array of pixels. The scintillators are coupled to the imager with their respective longitudinal axes parallel to each other. An incoming radiation beam that has passed through the object enters the scintillators through respective surfaces of the scintillators that are transverse to the longitudinal axes, and is converted by the scintillators into light that is received by respective subsets of the planar array of pixels.
