Zusammenfassung:
Tight-fit human head ultra-high field (UHF,>7T) 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 <16), 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,
~50 greater B , and ~30 greater SNR near the brain center as compared to common Tx-only/ Rx-only
(ToRo) array.
