Title:
X-RAY GENERATION DEVICE AND X-RAY IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/213039
Kind Code:
A1
Abstract:
An X-ray generation device comprising: an X-ray generation tube having a cathode that includes an electron emitting part which emits electrons in a first direction, and an anode that includes a target which generates X-rays due to the electrons emitted from the electron emitting part colliding therewith; a voltage supply part supplying voltage to the X-ray generation tube via a conductive wire; a housing container having a first section that forms a first space for housing the voltage supply part, a second section that forms a second space for housing the X-ray generation tube with said second space having a width that is narrower than that of the first space in a second direction perpendicular to the first direction, and a linking part that links the first section and the second section to one another such that the first space and the second space are in communication; and an insulating liquid filling an internal space in which the first space and the second space are in communication, wherein the linking part has a projection that projects toward the internal space, the cathode is disposed between the projection and the anode in the first direction, and an insulating member is disposed so as to enclose at least part of the conductive wire and block at least a linear path between the conductive wire and the projection.
