Surface loop transceiver head phased arrays improve
transmit efficiency in comparison to larger Tx-only
arrays due to tighter fit. However, the number of
elements is limited by the number of available
Tx-channels and decoupling issues, which compromises SNR
and parallel receive performance. As a proof of concept
we developed and constructed a novel splittable 9.4T
transceiver array. Splitting of each Tx-loop doubles the
number of Rx-elements without necessity of moving the
array away from the subject, which allows optimization
of both Tx and Rx performance at the same time.
Splitting in a larger number of Rx-elements, (e.g.4, 8),
is possible.
