摘要： A method for protecting an X-ray source including: a liquid jet generator configured to form a liquid jet moving along a flow axis; an electron source configured to provide an electron beam interacting with the liquid jet to generate X-ray radiation; the method including: generating the liquid jet: monitoring a quality measure indicating a performance of the liquid jet; identifying, based on the quality measure, a malperformance of the liquid jet; and if said malperformance is identified, causing the X-ray source to enter a safe mode for protecting the X ray source. Further, to corresponding devices.

摘要： The invention proposes an insulator within an X-ray tube having a vacuum side and an ambient side and a feedthrough substantially coinciding with an axis of symmetry at the vacuum side and an axis of symmetry at the ambient side. The axis of symmetry at the vacuum side and the axis of symmetry at the ambient side have an angle of at least 5°, preferably 90°, with respect to each other. An X-ray source comprising such an insulator is presented as well and the present invention also extends to a medical imaging apparatus for generating X-ray images of a patient thereby using an X-ray source with such an insulator. In an embodiment, an X-ray source is provided wherein the insulator is plugged to an electrical connector at the ambient surface.

摘要： An X-ray inspection device is configured to prevent water from flowing into areas of the X-ray inspection device during a washing operation. The X-ray inspection device is provided with an X-ray emitter, a cooler, a cooler cover, and an opening/closing member. The cooler cools the X-ray emitter. The cooler cover covers the cooler. Openings are formed in the cooler cover and, when open, provide interior-exterior air flow communication when the cooler is cooling the X-ray inspection device. An opening/closing member is configured for movement between an open orientation opening the opening and a closed orientation closing the openings formed in the cooler cover.

摘要： An X-ray inspection system that can simply and automatically perform aging without separately preparing a shutter moving member including a dedicated motor or a guide member for aging is provided. When power is supplied, a stage moves in X and Y directions by activating a stage moving mechanism, and an X-ray source stops at an aging position below an X-ray shielding plate disposed beside a support plate on the stage. In this state, aging is started. When the aging is ended, an input of an imaging instruction for X-ray imaging is waited for.

摘要： Provided is an X-ray apparatus and a method of controlling an X-ray apparatus capable of detecting a sign of breakage of a filament. A method of controlling an X-ray apparatus for performing control involving controlling a filament current flowing through a filament of a cathode part to maintain constant a tube current flowing between the cathode part and an anode part with a target, includes: monitoring the current value of at least one of the filament current and the tube current; detecting the mode of change in the current value; determining the presence or absence of a sign of breakage of the filament based on the mode of change in the current value; and issuing a warning based on the determination.
