This abstract describes our initial experiences using the parallel transmit (pTx) mode on our recently-installed 7T Terra MRI scanner (Siemens, Germany). We acquired data from a phantom and a human volunteer with a turbo-FLASH B1-mapping sequence and an EPI sequence. We used the conventional single-channel system with a Nova 32-channel 1Tx head coil and the pTx system with a Nova 32-channel 8Tx head coil. For the parallel-transmit system, the sequences were run in both a static CP+ B1 shim mode, and with dynamic online SPOKES-2 pulse design. We report temporal signal-to-noise ratio (tSNR) statistics for each image series.
