摘要： An arrangement for noninvasively detecting both alternating and direct biocurrents in a living organism applies a magnetic field to the organism, such that a biocurrent flowing in the organism interacts with the applied magnetic field to generate a force in the tissue of the organism at the location of the biocurrent, producing an acoustic response thereat. The acoustic response is detected by placing at least one acoustic transducer detector, such as a microphone, in proximity to the organism, such that the detected acoustic response corresponds to the biocurrent. The applied magnetic field can be generated by a circular array of magnetic field generators placed symmetrically about the organism. The applied magnetic field can be rotated relative to the organism by selectively energizing opposite pairs of magnetic field generators in sequence. An array of acoustic detectors can be placed in proximity to the organism, such that the timed response of each detector in relationship to the timed response of the other detectors or to the phase of the applied magnetic field provides information on the magnitude and location of the biocurrent.
