The 7T operating frequency of 1H and 19F RF transceivers is in far field regime, while for remaining nuclei these are in near-field regime. Consequently, the optimal setup for far field is based on antennas, while for near field these are based on loop coils. Owing to their intrinsic field orthogonality, these setups can be merged with low RF coupling and thus low penalty in efficiency as we demonstrated for a quintuple tuned head coil. Here we show that the design is generalized and can in principle be used for any body part, as demonstrated in brain, breast and extremity.
