Abstract:
In a radiation imaging apparatus, an envelope has a first window for transmitting radiation and is filled with an insulating liquid, and a radiation tube in the envelope has, at a position facing the first window, a second window for transmitting the radiation, and a shielding member. A solid insulating member is arranged between the shielding member and the inner wall of the envelope, and an opening is formed at a position on the insulating member corresponding to the first window. The shortest distance from the shielding member to the first window or the inner wall of the envelope through the opening of the insulating member without the insulating member is made to be longer than the shortest distance from the shielding member to the first window or the inner wall of the envelope through the insulating member, thereby improving withstand voltage performance without reducing an radiation amount.
Abstract:
Provided is an X-ray generator including an electron passage in an electron-passage forming member; and a target on an insulative substrate. The transmission X-ray generator irradiates the target with electrons that have passed through the electron passage to generate X-rays. The target is provided at a central region of the substrate; the electron passage accommodates a secondary-X-ray generating section that generates X-rays by irradiation with electrons reflected from the target; the secondary-X-ray generating section and the target are disposed so that both of X-rays generated by direct irradiation of the target with the electrons and X-rays generated by irradiation of the secondary-X-ray generating section with the electrons reflected from the target are radiated to the outside; and at least part of the peripheral region of the substrate has higher transmittance for the X-rays generated at the secondary-X-ray generating section than the central region of the substrate.

The radiation generating apparatus has an envelope 12 having a first window 27 for transmitting the radiation, a radiation tube 14 enclosed in the envelope 12 and having a second window 19 for transmitting the radiation at a position in opposition to the first window 27, and an insulating liquid 13 filled between the envelope 12 and the radiation tube 14. A solid-state insulating member 28 is placed between the first window 27 and its periphery and the second window 19 and its periphery.
Abstract:
An X-ray tube comprises: an envelope which has a cathode at one end and an anode at another end of a barrel of a tubular insulating tube and which has a sealed interior; an electron gun which is arranged inside the envelope and has a shape that protrudes from the cathode; and a target which is electrically connected to the anode and generates X-rays when being irradiated with electrons emitted from the electron gun. With reference to an end position that is a projection of a position of an end on the anode side of the electron gun onto an inner wall of the insulating tube, a mean wall thickness of the barrel is greater on the cathode side than on the anode side.
