The electric conductivity and permittivity of tissue can be helpful to predict of the local SAR distribution during MR measurements or can potentially be used as an additional diagnostic parameter. This study presents the new approach Electric Properties Tomography (EPT), which derives the patients electric properties from the spatial sensitivity distributions of the applied RF coils. Initial experiments on a standard MR system underline the principle feasibility of EPT. In contrast to previous conductivity / permittivity measurements, EPT does not apply external electrodes or currents and circumvents the solution of an inverse problem, potentially leading to improved spatial resolution.
