The image uniformity and signal to noise (SNR) is not high enough for extra-cranial imaging with the existing Head-Neck coil due to the limited channel number of the neck section. Traditionally, minimizing the coupling between nearest-neighbor coils is necessary for eliminating signal crosstalk. However, in this work, we propose an inductive coupling coil design to increase effective coverage without any signal interference, thereby breaking through the limitation of the channel number. Extra-cranial imaging has better image uniformity and 16.5% higher SNR using the new neck coil at 3.0T.
