Abstract
Methods and systems are provided for increasing a quality of computed tomography (CT) images generated by a CT system by altering a shape of a focal spot of an X-ray emitter of the CT system. In one embodiment, a method comprises controlling the CT system to focus a beam of electrons generated by a cathode of the CT system at a plurality of focal spots on a surface of an target of the CT system; generating a composite focal spot from the plurality of focal spots; and obtaining projection data of the CT system with the composite focal spot. For example, two focal spots may be combined to generate the composite focal spot. By combining focal spots to generate composite focal spots, a quality of a resulting view produced by the CT system may be increased.
