Publication number: 20140369460Abstract: 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.

Publication number: 20130195254Abstract: An X-ray control unit using a monocrystalline material which controls only a specific wavelength of X-rays, by using the monocrystalline material as a filter. The X-ray control unit includes a light source configured to generate X-rays, an X-ray control filter formed of a monocrystalline material having grown in one direction and configured to filter the X-rays generated by the light source to reflect and transmit characteristic X-rays, and an adjustor configured to adjust the light source and the X-ray control filter to arbitrary angles. Since X-rays having a specific wavelength can be selectively used by using a filter, the X-rays can be easily controlled and their intensity can be easily regulated. A characteristic line of the X-rays can be controlled and their intensity can be regulated without directly controlling an X-ray source.Type: ApplicationFiled: June 8, 2012Publication date: August 1, 2013Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Sungyoul CHOI, Yoon Ho Song, Jin Woo Jeong, Jun Tae Kang, Jae-woo Kim
