# Quantitative conductivity estimation using MR-EIT

*(bio-electromagnetism: material)*

For bio-electromagnetic simulations in general it is necessary to have as input conductivity values of the several tissues. Magnetic Resonance Electrical Impedance Tomography is a methodology that can be employed for quantitatively determine the conductivity of several tissues. Using advanced magnetic resonance sequences it is possible to induce eddy currents in human tissues. These eddy currents carry information with respect to the conductivity values and the magnetic fields resulting from these eddy currents can be measured in a MR scanner. Starting from these MR measurements it is possible to solve an inverse problem so to quantitatively determine the absolute conductivity values [5]. We aim at solving this inverse problem in an as accurate way. *[5] N. De Geeter, G. Crevecoeur, L.
