MR is not yet able to image the electric conductivity and permittivity of tissue. Yet, these parameters are typically measured using external electrodes, defining an inverse problem, leading to limited spatial resolution. This study presents a new approach Electric Properties Tomography (EPT), which derives the patients electric properties from the spatial sensitivity distributions of the applied RF coils. A principle proof of EPT might be feasible with no or only minor modifications of a standard MR. EPT is not based on an inverse problem, and thus, might be able to achieve images of higher quality than achievable with previous approaches.
