Abstract :
Magnetoacoustic impedance tomography with magnetic induction (MAT-MI) is a new imaging method. Its images reflect conductivity distribution. In this paper, we firstly proposed the numerical simulation method of multi-physics fields coupling to obtain the distribution of acoustic field in MAT-MI without the static magnetic field. Simple acoustic detection experiments are conducted to validate the algorithm. The results demonstrated its feasibility, and may provide some theoretical foundation for the further research on the real-time detection of acoustic signals and the reconstruction method of the MAT-MI.
