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.
