とを特徴とする、Ｘ線管。 It consists of an anode part and a cathode part that are vacuum-enclosed in an envelope. The cathode part supports a filament and has a focusing electrode that focuses the electrons emitted from the filament. The anode part supports acceleration from the cathode part, In an x-ray tube having a target that is collided with focused electrons, the filament is sectioned or divided along its length to control the current flow in the filament, with means for changing the bias on the focusing electrode to change the x-ray focal width on the target. An X-ray tube, characterized in that it is also equipped with means for changing the X-ray focal length by changing the portion through which the X-rays flow.
