Most transmit (TX) arrays used in parallel transmission can also be used as receive (RX) arrays, raising the question of optimal signal combination to recover RX field homogeneity. In this study, different approaches to signal combination are compared, using an 8-channel TX/RX body coil at 3T. The possibility to combine the signals of the individual channels in the image space resulted in greatly improved homogeneity compared to a single channel birdcage coil.
