Abstract
Methods and systems are provided for increasing a quality of computed tomography (CT) images. In one embodiment, a CT system comprises an X-ray tube and an X-ray controller including one or more processors having executable instructions stored in a non-transitory memory of the CT system that, when executed, cause the one or more processors to, during a first view of a CT scan of an object, focus an electron beam at a first focal spot on a target of the X-ray tube, the first focal spot of a first size; during a second view of the CT scan, focus the electron beam at a second focal spot on the target, the second focal spot of a second size different from the first size; and reconstruct an image of the object from projection data including the first view and the second view.
