We have developed a new decoupling method using a vertical loop for gapped phased-array coils. The vertical loop is placed between nearest-neighbor coils, and by changing the value of the capacitor in the vertical loop, decoupling can be easily achieved. We also fabricated a 3.0T 2-ch loop array with vertical loop and demonstrated its decoupling performance. The coupling S12 measured between the two coils was −28 dB. Phantom images showed no significant coupling between the coils. These results indicate that the proposed method can effectively decouple between the nearest-neighbor coils in gapped phased-array coils.
