Comparison, for a 32-element transmit array, of the case in which the entire space between the phantom and the coil is filled with HPM (Fully Filled), and the case in which only one half of this available space is filled (Half Filled). The optimal permittivity value was used for each case. A) L-curves for the two cases as well as the case with no HPM. B) A zoomed view highlighting similarities between the Fully Filled and Half Filled cases with appropriate adjusted optimum permittivity.
