A non-invasive magnetic resonance biomedical system

This paper proposes a pair of coils coupled by magnetic resonance coupling, which effectively induced a current at the biological medium for potential biomedical applications. Calculations and field estimation was done using finite element modeling software. Ferrite cores were added to the setup which showed larger induced current density in the tissue (more than 2 times) due to eddy current generation, as compared to the coils without core. Further, experiments were conducted with an animal tissue placed between two resonating coils, which showed similar results with an induced current of 0.07 mA using 1NI coil. Also, 1.6 times larger current was induced in the tissue when ferrite cores were used as compared to air core.
