<p>Shielded gradient coils are adapted for use in an MR imaging apparatus having spaced apart pole pieces. The x, y, and z coils each include active (40, 38, 36) and shield layers (32, 30, 34). The x-active (40) and shield (32) layers are interconnected by a plurality of vertical electrical connections (44) extending around the periphery of the coil. The y-active (38) and shield (30) layers are similarly connected (42). The z-active (40) and shield (34) layers each have a generally spiral conductor pattern. <IMAGE></p> |
