Abstract: The present disclosure may provide a micro X-ray tube with a filter tube to filter X-rays and at the same time to serve as an insulator. For this, the X-ray tube may include a filter tube between a second electrode and a gate electrode, hence separating from each other. The second electrode may have a target and the gate electrode may accelerate an electron-beam to collide with the target. The filter tube includes an alumina (Al2O3). The target is inclined to allow the X-rays to be directed toward the filter tube.

Abstract: Provided herein is a field emission device. The field emission device includes a cathode which is connected to a negative power supply and emits electrons, an anode which is connected to a positive power supply and includes a target material receiving the electrons emitted from the cathode, and a ground electrode which is formed to face the anode and has an opening through which the electrons emitted from the cathode pass. The ground electrode is grounded so that when an arc discharge occurs due to high voltage operation of the anode, electric charge produced by the arc discharge is emitted to a ground.

Abstract: A method and apparatus for generating X-rays that can acquire an X-ray image of a subject at a high speed are provided. When a CT system checks a subject, the CT system can acquire an X-ray image of the subject through rotating X-rays that are emitted from the X-ray generating apparatus and thus anX-ray image of the subject can be obtained in various angles. Further, because it is unnecessary for the X-ray generating apparatus or the subject to move relative to each other, an X-ray image can be acquired at a high speed and thus a subject can be rapidly checked.
