Abstract
A flat emitter configured for use in an X-ray tube is presented. The X-ray tube includes a first conductive section including a first terminal. Further, the X-ray tube includes a second conductive section including a second terminal. Also, the X-ray tube includes a third conductive section disposed between the first conductive section and the second conductive section, wherein the third conductive section is configured to emit electrons toward a determined focal spot, and wherein the third conductive section includes a plurality of slits subdividing the third conductive section into a winding track coupled to the first conductive section and the second conductive section, wherein at least two of the plurality of slits are interwound spirally to compose the winding track, and wherein the winding track is configured to expand and contract based on heat provided to the third conductive section.
