A multiloop coupled resonator coil design for MRI

The author describes the design of a head coil for use in MRI. The current in the coil is distributed over multiple coupled resonators to achieve both high sensitivity and field uniformity over a large volume. This coupled resonator coil had better uniformity than a saddle coil in all directions. Compared to a birdcage coil, it had similar uniformity in transaxial sections near and inferior to center, and better uniformity in transaxial sections superior to center. The coupled resonator coil was more uniform than the birdcage coil in sagittal sections
