Contour plots of TR (a, c, and e) and efficiency (b, d, and f) as functions of maximum gradient strength and slew rate, for single-echo SSFP imaging and low-resolution (a and b), normal-resolution (c and d), and high-resolution (e and f) scenarios. The dashed line in each case is the “optimum” operating point, which we calculated for a given slew rate by determining the maximum gradient strength at which further increases in gradient strength no longer improved speed performance or efficiency. The small square drawn in each graph indicates the operating point of most modern scanners (40 mT/m, 150 mT/m/ms).
