Each electron generator includes an emitter element to emit an electron beam, a meshed grid adjacent each emitter element to enhance an electric field at a surface of the emitter element, and a focusing element positioned to receive the electron beam from each of the emitter elements and focus the electron beam to form a focal spot on a shielded target anode, the shielded target anode structure producing an array of x-ray focal spots when impinged by electron beams generated by the plurality of electron generators. The plurality of electron generators are arranged to form an electron generator matrix that includes activation connections electrically connected to the plurality of electron generators, wherein each electron generator is connected to a pair of the activation connections to receive an electric potential therefrom.

    摘要: A system and method for addressing individual electron emitters in an emitter array is disclosed. The system includes an emitter array comprising a plurality of emitter elements arranged in a non-rectangular layout and configured to generate at least one electron beam and a plurality of extraction grids positioned adjacent to the emitter array, each extraction grid being associated with at least one emitter element to extract the at least one electron beam therefrom. The field emitter array system also includes a plurality of voltage control channels connected to the plurality of emitter elements and the plurality of extraction grids such that each of the emitter elements and each of the extraction grids is individually addressable. In the field emitter array system, the number of voltage control channels is equal to the sum of a pair of integers closest in value whose product equals the number of emitter elements.

    摘要: An integrated portable medical diagnostic system (PMDS) provides easy and convenient access to one or more medical instruments for healthcare practitioners. The PMDS is utilized in an outpatient workflow in which the practitioner generally remains stationary, while patients rotate to and from the practitioner over the course of a medical examination or procedure. The PMDS includes a body including a plurality of compartments, a first compartment defines a first receptacle for a blood pressure monitor, a second compartment adjacent the first compartment defines a second receptacle for an otoscope and an ophthalmoscope, and a third compartment adjacent the second compartment defines a third receptacle for a thermometer.
