    Abstract: A flat emitter configured for use in an X-ray tube is presented. The X-ray tube includes a first conductive section including a first terminal. Further, the X-ray tube includes a second conductive section including a second terminal. Also, the X-ray tube includes a third conductive section disposed between the first conductive section and the second conductive section, wherein the third conductive section is configured to emit electrons toward a determined focal spot, and wherein the third conductive section includes a plurality of slits subdividing the third conductive section into a winding track coupled to the first conductive section and the second conductive section, wherein at least two of the plurality of slits are interwound spirally to compose the winding track, and wherein the winding track is configured to expand and contract based on heat provided to the third conductive section.

    Abstract: The present inventors have recognized that fall times between high-kV to low-kV levels (during a “dual energy” or “fast-kV” energy scan) are linked to the discharge of HV (high voltage) capacitance. In an embodiment of the invention, a high voltage generator may be activated during fall transitions from first to second energy levels in order to substantially maintain a predetermined fall transition time. Accordingly, substantially equal energy distributions between high-kV and low-kV levels may be achieved.

    Abstract translation: 本发明人认识到，在高kV至低kV电平之间（在“双能量”或“快速kV”能量扫描期间）的下降时间与HV（高电压）电容的放电有关。 在本发明的一个实施例中，高压发生器可以在从第一到第二能级的跳变转变期间被激活，以便基本保持预定的下降转变时间。 因此，可以实现高kV和低kV电平之间的基本上相等的能量分布。

    Abstract: In accordance with one aspect of the present system, an X-ray detector of an X-ray imaging system includes a communication module configured to receive a pre-shot image from a detection circuitry and receive one or more pre-shot parameters from a source controller of the X-ray imaging system. The X-ray detector further includes an analysis module configured to determine one or more image characteristics of the pre-shot image. The X-ray detector further includes a determination module configured to calculate one or more main-shot parameters based on the one or more pre-shot parameters and the one or more image characteristics. The determination module is further configured to send the one or more main-shot parameters to the source controller of the X-ray imaging system.

    CPC classification number: H01J35/14

    Abstract: Issues related to maintaining the size of a focal spot on the target material of an X-ray source are addressed by linking the currents used in a magnetic focusing system employed in the X-ray source. The size of the focal spot on the target is less sensitive to current changes applied to the magnetic focusing system due to this linkage.
