  • Publication number: 20240016467
    Abstract: A method of determining performance characteristics of a breast compression paddle utilized in a breast imaging system includes receiving a force application signal, wherein the force application signal is associated with an application of a compressive force by the breast imaging system with the breast compression paddle to a breast of a patient. The method applies the force application signal to an algorithm to obtain a reduction value. The reduction value is subtracted from a known paddle performance value for the breast compression paddle to obtain an updated paddle performance value for the breast compression paddle.

  • Publication number: 20230251210
    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.

  • Patent number: 11510306
    Abstract: An x-ray tube having at least one focusing cup and an anode. The x-ray tube may have a first filament positioned in a first location between the focusing cup and the anode, the first filament having a first size, and a second filament positioned in a second location between the focusing cup and anode, the second filament having a second size that is substantially the same as the first size. The x-ray tube may also include a switching mechanism configured to engage the second filament upon failure of the first filament.
