The proportionality of the RF reception field to B1-* was demonstrated straightforwardly in the NMR experiments at 4.7 T. Maps of the reception field and B1- of a saline phantom were examined in magnitude and phase. After the reception field map was measured, the RF coil with the sample was rotated 180 degrees around the vertical axis and we measured the transmission field map, which corresponds to B1- in the original configuration. We also examined phases of the reception field maps in the original and inverted configurations. From these results we conclude the proportionality of the reception field to B1-*.
