Abstract
Magnetoacoustic tomography with magnetic
induction (MAT-MI) is one of the multiphysics imaging
techniques that combines the principle of magnetic field
excitation and acoustic vibration. It is a noninvasive imaging
technique developed in order to achieve high electrical
impedance contrast of biological tissue as well as high spatial
resolution close to ultrasound imaging. The feasibility to
reconstruct high spatial resolution conductivity images using
MAT-MI method has been demonstrated by both computer
simulation and experimental studies. This work reviews the
summary of fundamental ideas of MAT-MI and major
techniques developed in recent years. First, the physical
mechanisms underlying MAT-MI imaging are described
including the magnetic induction and Lorentz force induced
acoustic wave propagation. Second, experimental setups and
various imaging strategies for MAT-MI are reviewed. Finally,
we give our opinions on existing challenges and future directions
for MAT-MI research. With all the reported and future
technical advancement, MAT-MI has the potential to become an
important noninvasive modality for electrical conductivity
imaging of biological tissue.
