Abstract: An X-ray tube comprises a vacuum vessel; a cathode and an anode fixedly disposed inside the vacuum vessel; and a rotary mechanism that rotates the vacuum vessel. The cathode is disposed on the circumference with the rotary shaft of the rotary mechanism as its center and includes a plurality of cathode parts that can individually be turned ON/OFF. The anode includes parts opposite to the plurality of cathode parts, respectively.

Abstract: The X-ray tube disclosed herein includes an electron emission unit including an electron emission element using a cold cathode; an anode unit disposed opposite to the electron emission unit, with which electrons emitted from the electron emission unit collide; and a focus structure disposed between the electron emission unit and a target unit disposed on a surface of the anode unit that is opposed to the electron emission unit. The electron emission unit is divided into first and second regions which can independently be turned ON/OFF. The X-ray tube is focus-designed such that collision regions, at the anode unit, of electron beams emitted from the respective first and second regions substantially coincide with each other.
