Abstract
A rotating x-ray tube comprises an anode assembly having an anode target for distributing heat generated at a focal spot. The x-ray tube further comprises a cathode assembly for producing X-rays upon impact with the anode. A target angle matching cathode cup structure is associated with the cathode assembly. The angled cathode cup structure creates a parallel surface between the cathode and the target to provide a focused electron beam.
