Embodiment approach

[0015] figure 1 It is a cross-sectional view schematically showing an example of the X-ray tube device 1 of the embodiment.

[0016] The X-ray tube device 1 includes a tube container (hereinafter, referred to as a container or housing) 2 , an X-ray tube 3 , an insulating member 4 , a stator coil 5 , and sockets 20 ( 20L, 20R). The first direction X, the second direction Y, and the third direction Z are orthogonal to each other, but may intersect at an angle other than 90 degrees. Hereinafter, the plane defined by the second direction Y and the third direction Z will be referred to as "Y-Z plane". In addition, in the third direction Z, the arrow direction is referred to as the rear side (rear), and the direction opposite to the rear side is referred to as the front side (front). In the second direction Y, the direction of the arrow is referred to as an upper side (upper side), and the direction opposite to the upper side is referred to as a lower side (lower side). Hereinaft...

Abstract

Embodiments relate to an X-ray tube device. Provided is an X-ray tube device capable of improving insulation. The X-ray tube device of the embodiment comprises: a container; an X-ray tube, which is located at the inner side of the container and radiates X-ray; a socket, which is arranged in the container and is electrically connected to the X-ray tube, and extends towards a first direction and isformed into a cylindrical shape; an insert, which is inserted into the socket and electrically connected to the socket; insulating oil, which is filled into a space between the socket and the insert;and an elastic member, which is disposed at a position between the socket and the insert, seals the insulating oil filled in the space in a liquid-tight manner, and deforms based on the change of theinsulating oi.

Description

[0001] This application is based on Japanese patent application 2017-143854 (application date: July 25, 2017), and enjoys the priority of this application. This application refers to the aforementioned application and includes the entire content of the same application. technical field [0002] Embodiments relate to an X-ray tube device. Background technique [0003] In general, X-ray tube devices are used in medical treatment and the like. For example, a rotating anode type X-ray tube device is used as an X-ray tube source for gastric examination or CT image acquisition. The X-ray tube device includes an X-ray tube housed in a tube container (casing). The X-ray tube includes a cathode and a substantially umbrella-shaped anode target opposite to the cathode in a vacuum-environment enclosure. The cathode is provided at a position eccentric from the central axis of the X-ray tube. The anode target is rotatably installed around the central axis of the X-ray tube. The X-ray...
