Abstract:
1. An imaging system comprising: a rotatable gantry having an opening therein to receive a subject to be scanned and configured to rotate about a central axis in a rotation direction; a first x-ray source coupled to the rotatable gantry at a first position, wherein the first position is offset from the central axis of the rotatable gantry by a first distance; a second x-ray source coupled to the rotatable gantry at a second position, wherein the second position is offset from the central axis of the rotatable gantry by a second distance, offset from the first position in a direction coincident with the rotation direction, and offset from the first position in a direction parallel to the central axis; a first rotor coupled to the first x-ray source; a second rotor coupled to the second x-ray source, wherein the second rotor is constructed to rotate independently of the first rotor; a detector array comprising a plurality of detectors coupled to the rotatable gantry; and a computer programmed to:
