Comparative analysis between different approaches for electrical properties tomography

This paper presents a comparative analysis between three numerical methods used in the electrical properties tomography to reconstruct the conductivity and permittivity of biological tissues from the radiofrequency magnetic field map measurable in a magnetic resonance system. The analysis is performed on model problems, whose solution provides the magnetic field values to be used as virtual measurements. The effects on the result accuracy of very high and very low conductivity materials (mimicking the presence of medical implants) are finally evaluated.
