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.
