a The SAR10g maps and the local peak SAR10g values of the different birdcage coils. b The SAR efficiency maps of the different birdcage coils. The improved open-face birdcage demonstrated a 10.5% better SAR efficiency compared to the initial open-face birdcage coil and was comparable to the 16-rung standard birdcage coil.
