Abstract

According to one embodiment, an X-ray tube assembly includes a housing, an X-ray tube, a coolant to which at least a part of heat generated by the X-ray tube is transferred, a circulation channel through which the coolant is circulated, a circulation pump, a radiator, an air filter and a fan unit. The air filter is formed of a three-dimensional nonwoven fabric that is formed of irregularly tangled resin fibers and provides a three-dimensional structure having a spatial volume ratio of not less than 93%. The air filter permits air to pass therethrough to eliminate dust from the air.

Description

technical field [0001] Embodiments of the present invention relate to an X-ray tube device and an X-ray computed tomography device. Background technique [0002] A gantry of an X-ray computed tomography apparatus (hereinafter referred to as an X-ray CT apparatus) includes a fixed frame, a rotatable gantry rotatably supported by the fixed frame, and a case housing the fixed frame body and the rotatable gantry. The gantry also includes an X-ray tube device, an X-ray detector, and a cooling unit (cooler) mounted on the rotating gantry. [0003] More specifically, the rotary gantry has an annular frame portion, and an X-ray tube device, an X-ray detector, a cooling unit, and the like are attached to the inner wall of the annular frame. These units are more compact but have a higher mass, and the pressure on the setting surface is higher, so they especially need to be firmly fixed. [0004] By adopting the above structure, even when the rotary gantry rotates at a high speed and...
