摘要： An imaging system includes 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. The imaging system also includes 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. Further, the imaging system includes 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, wherein the second position is offset from the first position in a direction coincident with the rotation direction, and wherein the second position is offset from the first position in a direction parallel to the central axis.
