A system may comprise a plurality of imaging x-ray sources disposed in a fixed relation with respect to one another, each of the plurality of imaging x-ray sources to emit a respective imaging x-ray, an x-ray detector to acquire x-ray absorption projections of an object, each of the x-ray absorption projections associated with an imaging x-ray emitted by a respective one of the plurality of imaging x-ray sources, and a processor to perform digital tomosynthesis using the x-ray absorption projections to generate a cross-sectional image of the object. A method may comprise emitting a respective imaging x-ray from each of a plurality of imaging x-ray sources disposed in a fixed relation with respect to one another, acquiring x-ray absorption projections of an object, each of the x-ray absorption projections associated with an imaging x-ray emitted by a respective one of the plurality of imaging x-ray sources, and performing digital tomosynthesis using the x-ray absorption projections to generate a cross-sectional image of the object.
