Abstract

A method and apparatus are provided for adjusting a filament set height in a cathode of an x-ray tube. The method for adjusting a filament set height of a cathode comprises providing a cathode cup of an x-ray tube, the cathode cup comprising at least one bore extending therethrough; inserting a filament post through at least one bore such that the filament set height is below a desired filament set height; measuring an actual filament set height that results from the step of inserting; determining a filament set height adjustment distance in which the filament set height adjustment is generally equal to a difference between the actual filament set height and the desired filament set height; contacting an end of the filament lead with an adjustment tool; and moving the adjustment tool a distance substantially equal to the filament set height adjustment distance. Therefore, the filament is positioned at the predetermined filament set height.
