Recently, the principle feasibility of Electrical Properties Tomography has been shown at different field strengths, 1.5T, 3T, and 7 T. To determine the optimal field strength for EPT, a systematic study was performed comparing phantom measurements and simulations. The influence of SNR and the error induced by using the transceiver phase instead of the transmit phase on the reconstruction are evaluated.
