We demonstrate experimentally a new design of self-resonant tunable volumetric wireless coil based on a periodic array of coupled split-loop resonators. The wireless coil operates via inductive coupling with a birdcage coil enhancing the sensitivity of the latter at 1.5T and can be used for extremities imaging. Phantom and in-vivo wrist imaging with the proposed coil demonstrate 8.6 times higher transmit power efficiency in comparison with the birdcage coil and up to 2 times higher SNR versus standard receive-only coil.
