Low noise coupling is observed between an 8-channel transceiver and a 64-channel receiver array when loaded with the human. When compared to a 32-channel array, 1/g factor maps substantially improve, paving way to higher spatiotemporal resolutions.
A 64-channel high-density receiver array as shown is combined with an 8-channel transmit head-coil (not shown).
