A novel wireless phased array coil that is inductively coupled with the body coil is presented. This coil design eliminates the use of cables and all active components (such as pre-amps and active diodes). This design reduces the overall dimensions of the coils as well as drastically improves the workflow during imaging. Additionally, B1 field sensitivity was improved by 15 dB. SNR and volunteer imaging indicate that the proposed design demonstrate equal performance compared with available 12-channel head coils. Finally, the lack of coil ID requirement enables the coils to work on any OEM MR system at the particular field.
