We show for the first time that a metamaterial inspired, volumetric wireless coil demonstrates similar performance as the same size, cable-connected volume transceiver coil for extremities MRI at 1.5T. Numerical analysis and in vivo human wrist imaging with the wireless coil showed proper quality images with no artefacts and the same transceive efficiencies, while the global radiofrequency safety was 190% higher, compared to the commercial extremity coil.
