Abstract
A system includes at least one first magnetic field sensor configured to measure first and second magnetic fields. The system also includes at least one second magnetic field sensor configured to measure the second magnetic field substantially without measuring the first magnetic field. The system further includes processing circuitry configured to perform signal cancellation to generate measurements of the first magnetic field and to generate an output based on the measurements of the first magnetic field. The sensors could represent magneto-electric sensors. The magneto-electric sensors could be configured to up-convert electrical signals associated with the first and/or second magnetic fields to a higher frequency. The processing circuitry could be configured to identify one or more problems associated with a patient's heart.
