X-ray tube is an air evacuated vacuum tube that converts electrical energy to produce other forms of radiation including x-rays which are used for imaging purposes. The x-ray tube consists of different parts and elements which includes two basic and principle elements: a cathode and an anode. The cathode provides source of electrons that are received by the anode, to produce and release x-rays. Other elements of an x-ray tube include an air evacuated vacuum tube also known as the envelop, tube housing, a rotor, an induction motor, and other components such as cooling oil and expansion bellows.
