1. A method to map a biological tissue of alternating electrical polarity, the method comprising the steps of:
- transmitting a plurality of acoustic waves at a frequency though the biological tissue of alternating electrical polarity having a boundary between a depolarized portion and a nondepolarized portion;
detecting a variation in a magnetic field generated in response to the plurality of acoustic waves causing compression and rarefaction of the boundary;
measuring the variation in the magnetic field at the frequency of the plurality of acoustic waves;
translating the variation in the magnetic field at the frequency to a map of an electrical activity of the material; and
generating a display illustrative of the electrical activity of the biological tissue.

9. A system, comprising:
-
a transducer probe configured to transmit a plurality of acoustic waves at a frequency through a biological tissue of alternating electrical polarity having a boundary between a depolarized portion and a non-depolarized portion; a receiver operable to detect a variation in an magnetic field generated in response to the plurality of the acoustic waves causing compression and rarefaction of the boundary, the receiver configured to detect the variation in the magnetic field at a frequency substantially same to the frequency of the plurality of acoustic waves transmitted; a computer in communication with the transducer probe and the receiver, the computer operable to translate the variation in the magnetic field at the frequency to a map of an electrical activity of the biological tissue; and a display in communication with the computer, the display operable to illustrate the map of the electrical activity of the biological tissue. - View Dependent Claims (10, 11, 12, 13, 14, 15)
