Abstract
In this letter, we have proposed a new theory on mechanism of the magnetoacoustic (MA) signal generation with magnetic induction for an object with an arbitrary shape. An object under a static magnetic field emits acoustic signals when excited by a time-varying magnetic field, and the acoustic waveform is mainly generated at the conductivity boundaries within the object. The proposed theory on the MA tomography with magnetic induction produced highly consistent results among computational and experimental paradigms in a two-layer sample phantom and suggested the potential applications for bioimpedance imaging.
