Gradient coils have previously been designed with spread wires using the minimax|j| technique. These coils exhibit more evenly distributed temperatures than standard coils and are more efficient when limited by a minimum wire spacing. Here we investigate the application of the minimax|j| technique to whole-body shielded gradients of varying length and demonstrate that it can produce more efficient gradient coils when their length is very short.
