Multi-channel transmit arrays are essential at ultra hifh fields (UHF) to gain B1+-field control and to support parallel transmission. We combined a dedicated 16 channel transmit array with a 32 channel receive only array in a tightfitting modular coil housing. Results demonstrated excellent coil separation , whole brain coverage and SNR. The achievable homogeneity is significantly improved compared to a 1TX32RX whole brain coil (Nova Medical, Wilmington,MA,USA). The major advantage of the presented coil is increased pTX capability due to a dual row Tx design and significantly improved task presentation.
