1. A method for a computed tomography (CT) system, comprising:
controlling an X-ray source of the CT system to create a desired distribution of electrons striking a target of the CT system at each view of a subject, the desired distribution forming a composite focal spot, the composite focal spot including a first focal spot having a first distribution of electrons striking the target and a second focal spot having a second distribution of electrons striking the target, wherein a center of the first focal spot is separated from a center of the second focal spot;
obtaining projection data from X-rays generated as a result of electrons of the desired distribution of electrons striking the target; and
reconstructing an image from the projection data.
