Abstract :
Magnetoacoustic tomography with magnetic induction (MAT-MI) is a technique for imaging electrical conductivity in tissue. A time-varying magnetic field induces currents that interact with a static magnetic field to produce a Lorentz force, initiating ultrasonic waves. The goal of this communication is to examine the effect of anisotropy during MAT-MI.
