One of the challenges of designing coil arrays is to obtain sufficient decoupling among closely placed resonant elements. A novel technique for decoupling phased array coils without overlapping the nearest coil pairs is presented, which is based on the addition of additional resonant elements. A prototype of the proposed design has been built. The decoupling measured between two coils was better than -35 dB, showing that the mutual inductance is well minimized. MR experiments were performed on a 9.4 T MR System (Brucker Biospec 94-21), the MR images showed that this design is suitable for realizing arrays for parallel imaging at ultrahigh fields.
