The present invention relates to a portable X-ray tube, and more particularly, to a portable X-ray tube capable of miniaturization and weight reduction by reducing the structural volume of the X-ray tube by installing cathodes in the same direction together with the fixed anode. The portable X-ray tube comprises: an anode portion comprising an anode heat sink for conducting and dissipating heat transferred through the anode, an anode formed on the upper part of the anode heat sink, and an anode target formed on the inclined surface of the upper end of the anode; a cathode portion installed in parallel with the anode through the installation hole of the cathode portion formed in the anode heat sink; and a vacuum bulb fixed to the heat sink to seal the anode portion and the cathode portion with a vacuum; wherein the X-rays emitted through the anode target are irradiated to the upward direction as the installation direction of the anode.

X-ray tube systems and methods are described herein. A system for creating a vacuum environment in an X-ray tube assembly includes a vacuum tube having a first end and a second end, the first end of the vacuum tube welded to a support plate of the X-ray tube assembly, and the second end of the vacuum tube is pinched off or cold pressed to seal the vacuum environment within the X-ray tube insert of the X-ray tube assembly. A method of creating a vacuum within an X-ray tube assembly includes welding a first end of a vacuum tube to a support plate of the X-ray tube assembly, coupling a second end of the vacuum tube to a vacuum pump, using a vacuum pump to create a vacuum environment in the X-ray tube assembly and pinching off the second end of vacuum tube to seal the vacuum environment.

Implantable medical devices including a housing that contains operational circuitry for the implantable medical device and a dispensed hydrogen getter. The hydrogen getter may include a getter carrier material and one or more getter materials carried as suspensions in the getter carrier material, with the getter materials taking the form of organic compounds, such as fatty acids, or powdered metal oxides, or combinations thereof. The hydrogen getter may instead be comprised of two fatty acids having different melt temperatures. The hydrogen getter may be dispensed onto an encapsulant layer or other component of the implantable medical device, or may be blended into an encapsulant layer.
