The reconstruction of tissue electrical conductivity distribution has been in wide research in recent years as an indicator of underlying physiological and pathological conditions. For example the conductivity of breast cancer tissue has been seen to be significantly greater than the surrounding normal tissue [1]. In addition the knowledge of biological tissue impedance is of great interest to researchers doing electrical source imaging. Various techniques used for imaging tissue conductivity include electrical impedance tomography [2], magnetic resonance electrical impedance tomography [3], magnetic induction tomography [4], magneto-acoustic tomography [5], hall effect imaging [6], and the recently explored magnetoacoustic tomography with magnetic induction [7–10]. Of these techniques magnetoacoustic tomography with magnetic induction (MAT-MI) combines the high spatial resolution of ultrasound imaging with the good contrast provided by the conductivity variation in biological tissue...
