    摘要: A cathode header optic for an x-ray tube includes an elongate trench with opposite trench walls. A cup recess is formed in the trench between the opposite trench walls, and has a bounded perimeter. A cathode element is disposed in the trench at the cup recess. The cathode element is capable of heating and releasing electrons. A secondary cathode optic defining a cathode ring can be disposed about the header optic. The cathode optics can form part of an x-ray tube.

    摘要: An X-ray source includes a magnetic appliance to provide electron beam focusing. The magnetic appliance can provide variably focused and non-focused configurations. The magnetic appliance can include one or more electromagnets and/or permanent magnets. An electric potential difference is applied to an anode and a cathode that are disposed on opposite sides of an evacuated tube. The cathode includes a cathode element to produce electrons that are accelerated towards the anode in response to the electric field between the anode and the cathode. The anode includes a target material to produce x-rays in response to impact of electrons.

    摘要: A planar filament comprising two bonding pads and a non-linear filament connected between the two bonding pads. The planar filament may be wider in the center to increase filament life. The planar filament can form a double spiral-serpentine shape. The planar filament may be mounted on a substrate for easier handling and placement. Voltage can be used to create an electrical current through the filament, and can result in the emission of electrons from the filament. The planar filament can be utilized in an x-ray tube.
