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.

Abstract: An emitter device having an emission surface includes a plurality of ligaments configured to emit electrons in response to an applied electric field resulting from an applied electrical voltage. Further, the emitter device includes a plurality of slots configured to provide physical separation between two or more adjacently disposed ligaments of the plurality of ligaments, where one or more slots of the plurality of slots define an electrical path. Moreover, the emitter device includes a low work function layer disposed on at least a portion of a ligament of the plurality of ligaments.
