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 an X-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.
Claims11
An X-ray generating apparatus of a computer tomography (CT) system, the X-ray generating apparatus comprising:
- an electron source that generates electron beams in a z-direction of a three-dimensional space;
- a beam deflecting unit that deflects the electron beams by a predetermined angle in the z-direction by transferring a force in an x-direction or a y-direction of the three-dimensional space to the electron beams;
- and
- a target unit that emits X-rays by colliding with the electron beams.
A method of generating X-rays of a CT system, the method comprising:
- generating electron beams in a z-direction in a three-dimensional space;
- deflecting the electron beams by a predetermined angle in the z-direction by transferring a force in an x-direction or a y-direction to the electron beam;
- and
- emitting X-rays by colliding the electron beams with a target.
A CT system, comprising:
- an X-ray generating apparatus that generates X-rays rotating on an xy-plane of a three-dimensional space about a z-axis of the three-dimensional space;
- a detection unit that detects formed X-ray images after the rotating X-rays are transmitted through a subject;
- and
- a controller that configures a three-dimensional image by combining the detected X-ray images.
