A system includes emission of first radiation from a plurality of radiation sources disposed in a fixed relationship to each other, the first radiation emitted from a first plurality of locations defining a first array geometry. A first set of projection images is acquired based on the emitted first radiation and digital tomosynthesis is performed on the first set of projection images to generate a first cross-sectional image. Second radiation is emitted from the plurality of radiation sources disposed in the fixed relationship to each other, the second radiation emitted from a second plurality of locations defining a second array geometry. A second set of projection images is acquired based on the emitted second radiation, and digital tomosynthesis is performed on the second set of projection images to generate a second cross-sectional image. The first array geometry and the second array geometry differ in at least one of shape and size.
