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.
