Abstract: An X-ray source includes an X-ray tube; a radiation shielding shell enclosing the X-ray tube, the radiation shielding shell including a collimator formed integrally with it, wherein the radiation shielding shell comprises finely dispersed powder, polyester or epoxy resin and hardener; a cooler system providing oil to the X-ray tube; and an oil filled tank supplying the oil to the cooler system. There is a central shielding element shaped as a cylinder inside the radiation shielding shell and one or more end shielding elements around the X-ray tube. The central and end shielding elements are made of lead.

Abstract: An X-ray imaging system includes a frame; a gantry mounted on the frame; an electromagnetic linear drive coupled to the gantry for translating the gantry in a horizontal direction; a C-arm mounted on the gantry, the C-arm rotatable across at least a 90 degree angle; an X-ray source mounted to one end of C-arm; an X-ray detector array mounted to the opposite end of the C-arm. The array is formed of a plurality of array elements, each array element formed of a plurality of linear detectors. Each array element is mounted perpendicular to a radial line between a focal spot of the X-ray source and a middle of each array element, and the X-ray detector array has a focal point at the X-ray source.
