Title:
X-RAY TUBE DEVICE AND X-RAY IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/171234
Kind Code:
A1
Abstract:
In order to provide an X-ray tube device having a configuration which is capable of shielding X-rays without reducing cooling efficiency and provide an X-ray imaging device in which the X-ray tube device is installed, a device is equipped with: a cathode (211) which discharges an electron beam; an anode (212) which, by the electron beam colliding therewith, emits X-rays from a focal point that is the collision point with the electron beam; a vacuum envelope (213) which houses the cathode (211) and the anode (212) in a vacuum atmosphere; a housing (220) which supports the vacuum envelope (213) along with a cooling medium; and an X-ray shield (500) which is provided between the vacuum envelope (213) and the housing (220) and blocks the X-rays emitted from the focal point, and which is provided along the direction of flow of the cooling medium.
