Implementing diode detuning on transmit coils is complicated and leads to a loss in efficiency on the transmit side. It has been common practice to include it nevertheless with the aim of preventing loss of receive efficiency and noise correlation between receiver through coupling via the body coil. However, nowadays, receiver coil elements are orders of magnitude smaller so flux linkage is intrinsically low. Moreover, the operating frequency is high to maintain strong tissue-loading, and finally preamplifier decoupling is applied to reduce the effects of mutual coupling. Here we show the coupling to receiver arrays for three non-detuned body coils.
