In birdcage RF Body coils the endrings are typically in a high dB/dt area of the gradient coil. Both rungs and endring segments can be slotted to prevent gradient eddy currents, but it is not clear how to cut the transfer area where the rungs meet the endring. This paper examines several shapes of this transfer area and their impact on SNR and heat generated by the eddy currents.
