1. A biased cathode assembly of an X-ray tube, comprising:
an emitter assembly including a cathode cup, at least one emitter insulator, and an emitter;
an electrode assembly including at least one bias electrode and at least one bias electrode insulator;
at least one heat shield positioned between the emitter and the at least one bias electrode insulator, wherein the at least one heat shield is cylindrical;
wherein the cathode cup, the at least one emitter insulator, and the emitter are independent components that are coupled together;
wherein the at least one bias electrode and the at least one bias electrode insulator are independent components that are coupled together; and
wherein the emitter assembly is coupled to the electrode assembly.
