 Abstract: We evaluated the performance of several MRI radiofrequency dual-row transmit arrays with a range of overlapping distances, head positions, and tuning conditions. For the geometries, excitation conditions and volume of interest that were investigated, location of the volume of interest in middle of the coil and a small - 10 mm - overlap is preferable. The results provided confirm that with the preferable setup, safety excitation efficiency is practically insensitive to tuning condition, and head position, thus the safety margin can be relative small, allowing shorter scan times.
