N2 - Magnetoacoustic tomography with magnetic induction (MAT-MI) is an emerging technique, which collects ultrasound signals by inducing Lorentz force-based vibrations inside biological tissues to reconstruct electrical impedance properties with high spatial resolution. However, previous MAT-MI imaging systems only acquired small amplitudes of ultrasound signals as biological tissues are poor conductors of electricity, which limits the generated eddy current. In this work, we report our pilot MAT-MI experimental study in a magnetic resonance imaging scanner. The present experimental results suggest that MAT-MI under high static magnetic field environment is able to differentiate tissue electrical impedance with improved imaging contrast.
