ABSTRACT:
Cathode cup assemblies for an x-ray tube are described. In one embodiment, the cathode cup assembly includes a cathode cup and a focus tab. The cathode cup includes filament receiving channels, and each channel is sized to receive a filament. The focus tab is a plate having a filament aligning aperture. The focus tab cooperates with the cathode cup so that a periphery of the filament aligning aperture limits the positioning of the filaments within the filament receiving channels.
