Abstract
Various systems are provided for a cathode of an X-ray imaging system. In one example, a shield for a cathode comprises a cathode mask comprising a u-shaped central opening configured to receive a cathode cup, where a perimeter of the u-shaped central opening comprises a rolled over edge.
Claims13
A cathode assembly for an x-ray device, comprising:
- a cathode cup housing a focusing element of the cathode cup;
- a plurality of coiled filaments positioned in the focusing element;
- and
- a cathode shield comprising a cathode mask comprising a u-shaped central opening configured to receive the cathode cup, the u-shaped central opening centered over a lateral line of symmetry of the cathode mask, where a perimeter of the u-shaped central opening comprises a rolled over edge.
