Previously, a modular approach has been suggested for designing large arrays. It is based on a stacked combination of loop coils and microstrip transmission-line (MTL) elements, which are intrinsically orthogonal. In this work, this concept was adopted to build a helmet-shaped, dual-tuned array coil for human brain 31P spectroscopy and 1H decoupling and imaging at 3 T. The 1H channel is based on a pure MTL design with four spokes. On each spoke, a loop coil was added to permit 31P transmission/reception (Tx/Rx). Initial results from investigations of the performance for 31P MRSI including phantom studies are presented.
