  • Patent number: 12310734
    Abstract: An apparatus for measuring magnetic fields from a subject's organ comprises a plurality of unshielded magnetometers in a three-dimensional arrangement. A respective pair of magnetometers, in the plurality of magnetometers, has a respective known separation. Each magnetometer in the plurality of magnetometers is configured to simultaneously detect a biomagnetic field from at least a portion of the subject's organ and a background magnetic field and output a signal indicative of the detected biomagnetic field and the background magnetic field.

  • Publication number: 20250000416
    Abstract: A computer system receives a plurality of signals corresponding to first time-series magnetic data generated from a plurality of unshielded magnetometers proximate to the human subject. The first time-series magnetic data corresponds to magnetic fields generated from the human subject. The plurality of signals includes contributions from a biomagnetic field from at least a portion of the subject's organ and a background magnetic field. The computer system synchronizes the first time-series magnetic data to a common clock to generate synchronized time-series magnetic data. The computer system applies one or more filters to the synchronized time-series magnetic data to obtain filtered data. The computer system applies one or more noise reduction techniques to the filtered data to generate updated time-series magnetic data.
