An imaging system includes a radiation source, a positioner configured to rotate the radiation source along an arc path at a rate that is less than 0.4 degree/sec, an imager in operative position relative to the radiation source, wherein the radiation source and the imager are configured to obtain a plurality of images while the radiation source is at different positions along the arc path, and a processor configured to determine a digital tomosynthesis image using a subset of the plurality of images. An imaging method includes generating a control signal to control a positioner to rotate a radiation source through an arc path at a rate that is less than 0.4 degree/sec, obtaining a plurality of images that are generated using radiation from the radiation source while the radiation source is at different positions along the arc path, and determining a digital tomosynthesis image using a subset of the plurality of images. |
