We report a volume coil consisting of 16 bowtie slot elements arranged in eight independent modules. The slot coils provide several interesting advantages over conventional elements. In particular they demonstrate a high degree of Intrinsic coupling between modules, making this array ideally suited for use in parallel transmit using conventional amplifiers. Additionally, all match and tune elements, baluns and feedlines are concealed between two ground planes, shielding the imaging volume from stray electric fields. Imaging results are shown at 4.7 Tesla demonstrating isolated patterns and a broad coverage in volume coil mode.
