Abstract: An x-ray diffraction imaging (XDI) system having a system axis includes at least one x-ray source configured to generate x-rays directed toward an object that includes at least one substance. The at least one x-ray source is further configured to irradiate at least one voxel defined within the object with x-rays arriving from a plurality of directions, each direction defined by an angle of incidence with respect to the system axis. The system also includes at least one detector configured to detect scattered x-rays after the x-rays have passed through the object. The system further includes at least one processor coupled to the at least one detector. The processor is programmed to generate a plurality of XDI profiles of the object voxel. Each XDI profile is a function of an associated angle of incidence.

Abstract: A device for generating X-rays includes at least one electron source for the emission of an electron beam that defines a plane having a predetermined width value in a width dimension and a predetermined length value in a length dimension. The width dimension is substantially perpendicular to the length dimension. The device also includes at least one window frame at least partially defining at least one liquid metal flow path. The device further includes at least one electron window coupled to the at least one window frame. The at least one electron window is positioned within the at least one liquid metal flow path and is configured to receive the electron beam. The at least one electron window emits X-rays in response to an incidence of electrons thereon. The at least one electron window includes a surface curved in at least one of the width dimension and the length dimension.

Abstract: A multi-stage screening system for screening a container includes a pre-screening stage including a transmission X-ray device. The pre-screening stage is configured to generate constraint data associated with the contents of the container. The system also includes a screening stage including an X-ray diffraction imaging (XDI) device. The screening stage is configured to generate image data associated with the contents of the container. The system further includes a communication system coupled to the pre-screening stage and the screening stage. The communication system is configured to receive and transmit the constraint data and reconstruct at least one image of the container at least partially as a function of the constraint data and the image data.
