In a helmet-style head array coil consisting of loop-coil elements, some coil elements are nearly vertical to the z-axis making a blind region around the central axis of the loop coil. We propose a surface coil structure that consists of two parallel conductor planes to be placed vertically to the z-axis. We use the B1 components parallel to the conductor planes at one side of the coil. The vertical planar coil does not produce a blind region near it. Through phantom and human brain imaging experiments, we compared the imaging performances between a conventional loop coil and the proposed coil.
