32-Channel Combined Surface Loop / \textquotedblleftVertical”Loop Tight-Fit Array Provides for Full-Brain Coverage, High Transmit Performance, and SNR Improvement at 9.4T: an Alternative to Surface Loop / Dipole Antenna Combination
{Tight-fit human head ultra-high field (UHF,\textgreater7T) transceiver (TxRx) surface loop phased arrays improve transmit (Tx)-efficiency in comparison to Tx-only arrays, which are larger to fit receive (Rx)-only arrays inside. A drawback of the TxRx-design is that the number of array elements is restricted by the number of available RF Tx-channels (commonly \textless16), which limits the Rx-performance. A new 32-element tight-fit human head array, which consists of 18 TxRx-loops and 14 Rx-only vertical loops, was constructed. The array provides for full-brain coverage, \textasciitilde50 greater B , and \textasciitilde30 greater SNR near the brain center as compared to common Tx-only/ Rx-only (ToRo) array.}
