In order to allow for improved SNR and higher
acceleration during image acquisition in the body at 7T, we present a coil with
8Tx/Rx microstrip line elements with meanders and 24Rx loop elements. This coil
comprises 8 building blocks each consisting of one Tx/Rx element and 3
overlapping loops which are actively detuned during transmit. With about
-19 dB reflection and an average decoupling of more than -30 dB, the
SNR can be boosted by about 21% in the abdomen. Evaluation of g-factors as well
as in vivo images of healthy volunteers in both abdomen and heart show
promising results.
