Abstract
A segmented thermionic emitter is provided. The segmented thermionic emitter has, among other features, a plurality of segments substantially spanning an entire length of the thermionic emitter and aligned substantially parallel with one another. In one embodiment, the segmented thermionic emitter may allow milli-amp modulation of an X-ray tube at voltages less than approximately 2 kV.
