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.
