Abstract
Radiographic imaging systems and/or methods embodiments capable of both tomosynthesis x-ray imaging and general projection radiography x-ray imaging can include a single x-ray source assembly including a plurality of distributed x-ray sources, where at least one of the plurality of distributed x-ray sources is configured to output a beam sufficient for standard projection radiography, and each of at least two of the plurality of distributed x-ray sources is configured to output a beam at a lower radiation dose sufficient for tomosynthesis. In one embodiment, radiographic imaging systems and/or methods embodiments can include a single x-ray source; a first collimator that is configured to be adjustable for at least two dimensions; and a second collimator that is configured to provide fixed collimation. In one embodiment, a single x-ray source can include a single radiation shield or a single vacuum chamber.
