Abstract: A rotary-transmission-target microfocus X-ray source and an X-ray generation method based on the rotary-transmission-target microfocus X-ray source are provided. The X-ray source comprises a chamber, and an electron beam system is installed in the chamber. The electron beam system is arranged on a same side as an anode target rotating shaft. A motor in a rotary anode target system drives an anode target to rotate through a bevel gear transmission device. The microstructure of a target is designed. An electron beam emitted by the electron beam system vertically bombards the metal target of the rotating anode target. A cooling system is configured to cool the anode target.

Abstract: An x-ray tube can include an x-ray window sealed to a mount. An inner-collimator can be adjacent to, but not sealed to, the x-ray window. The inner-collimator can be sandwiched between the x-ray window and an insulating-layer. The insulating-layer can span an inner-collimator-aperture of the inner-collimator, forming an isolated cavity at the inner-collimator-aperture. Walls of the cavity can include the x-ray window, the inner-collimator, and the insulating-layer. The x-ray tube can have a light weight, can block x-rays in undesirable directions, and can shape the x-ray beam.

Abstract: Various methods and systems are provided for an X-ray tube cathode focusing element. In one example, a focusing element is configured with a first side positioned adjacent to an electrode plate. An insulator having a first side is positioned adjacent the electrode plate and a second, opposite side adjacent to a cathode base. The focusing element has at least three filaments of different sizes positioned in respective channels of different widths, where each of the at least three filaments are coupled to two current feedthroughs, each current feedthrough configured with a leg extending through a central, hollow space of the focusing element, the electrode plate, the insulator, and the cathode base.
