PURPOSE To investigate the effect of magnetic field strength on the validity of two assumptions (namely, the "transceive phase assumption" and the "phase-only reconstruction") for electrical properties tomography (EPT) at 1.5, 3, and 7T. THEORY Electrical properties tomography is a method to map the conductivity and permittivity using MRI; the B1 (+) amplitude and phase is required as input. The B1 (+) phase, however, cannot be measured and is therefore deduced from the measurable transceive… CONTINUE READING
