This is achieved by performing an optimization problem with the peak E\u2010field as the objective function and current amplitudes as unknown variables. Coil dimensions and winding patterns are fixed throughout the optimization, whereas other engineering metrics remain adjustable. Various scenarios are explored by manipulating adjustable parameters.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The array design consistently yields lower E\u2010fields and higher PNS thresholds across all scenarios compared with a conventional coil. When the gradient array coil generates target gradient fields within a 44\u2010cm\u2010diameter spherical ROL, the maximum E\u2010field is reduced by 10%, 18%, and 61% for the X, Y, and Z gradients, respectively. Transitioning to a smaller ROL (24\u2009cm) and relaxing the gradient linearity error results in further E\u2010field reductions. In oblique gradients, the array coil demonstrates the most substantial reduction of 40% in the Z\u2013Y direction. Among the investigated scenarios, the most significant increase of 4.3\u2010fold is observed in the PNS thresholds.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
