We designed 1 T/m gradient coils for a 14.1 T magnetic resonance microscope. The calculated contour wire pattern, however, should be transformed to a traversable wire path for actual construction. In this study, we optimized a connecting method by comparing three loop connecting patterns with the inside and outside return paths as a function of the transition size. We found that larger transition size in smooth parts of the loop reduced more the root mean square of deviations from the center gradient value. This optimization is applicable to gradient coils of larger size.
