X-ray tube

摘要

An X-ray tube is provided. The X-ray tube includes a first housing including an X-ray window formed therein, a second housing being rotatable about a rotational shaft installed within the first housing, an anode installed on the rotational shaft within the second housing and positioned in one side of the rotational shaft in an extending direction of the rotational shaft, an emitter installed on the rotational shaft within the second housing, positioned in the other side of the rotational shaft in the extending direction of the rotational shaft, and emitting electron beams, a lens unit installed between the anode and the emitter and focusing the electron beams emitted from the emitter to the anode, and an electron beam deflection unit installed on the rotational shaft to deflect an angle of electron beams moving toward the anode from the lens unit.
