Abstract
Various methods and systems are provided for an X-ray tube cathode focusing element. In one example, a focusing element is configured with three electron emission filaments, an integrated edge focusing, and a bias voltage. The integrated edge focusing may include a continuous single architecture with rounded edges, and a voltage of the focusing element may be negatively biased relative to a voltage of the electron emission filaments.
