  • SYSTEMS AND METHODS FOR ADAPTIVELY CONTROLLING FILAMENT CURRENT IN AN X-RAY TUBE
    Publication number: 20260101427
    Abstract: Systems and methods of adaptively controlling filament current in an x-ray tube of an imaging system include the x-ray tube having a filament being calibrated. Calibration data from the calibration of the x-ray tube is stored at the imaging system, the calibration data including a filament current value that determines a tube current value for a tube voltage value at a plurality of stations. A resistance value of the filament over a period of time is monitored. A change in the resistance value of the filament over the period of time is determined, and the filament current value of at least one of the plurality of stations is adjusted based on the changed resistance value.
    Type: Application
