연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The x-ray generating system of claim 5, further comprising a fourth fan disposed within the second cover of the housing, wherein the fourth fan is operable for forcing cooling air into the chamber and creating a positive pressure within the chamber.7. The x-ray generating system of claim 4, further comprising a third vent disposed within the second cover of the housing, wherein the third vent is operable for exhausting heated air from the chamber.8. The x-ray generating system of claim 7, further comprising a fourth vent disposed within the second cover of the housing, wherein the fourth vent is operable for exhausting heated air from the chamber.9. The x-ray generating system of claim 1, further comprising a second exhaust vent disposed within the lower portion of the housing, wherein the second exhaust vent is operable for exhausting heated air from the chamber.10. The x-ray generating system of claim 1, further comprising a heat exchanger disposed adjacent to the x-ray generating device and the first vent, wherein the heat exchanger is operable for drawing heat from the x-ray generating device and exhausting heated air from the chamber through the first vent.11. A computed tomography (“CT”) system, comprising:a gantry housing defining a gantry chamber, wherein the gantry housing comprises a lower portion, an upper portion, and a first gantry cover disposed adjacent to the upper portion of the gantry housing; an x-ray tube disposed within the gantry chamber, wherein the x-ray tube is operable for generating x-rays and residual heat; a first fan disposed within the first gantry cover of the gantry housing, wherein the first fan is operable for forcing cooling air into the gantry chamber and creating a positive pressure within the gantry chamber; a first vent disposed within the first gantry cover of the gantry housing, wherein the first vent is operable for exhausting heated air from the gantry chamber; and a first exhaust vent disposed within the lower portion of the gantry housing, wherein the first exhaust vent is operable for exhausting heated air from the gantry chamber. 12. The CT system of claim 11, further comprising a second fan disposed within the first gantry cover of the gantry housing, wherein the second fan is operable for forcing cooling air into the gantry chamber and creating a positive pressure within the gantry chamber.13.
