Distribution statistics for the experimental phantom maps of the $B_1^{+}-\text{dependent}$ factor F found on the right side of Fig. 11. The mean of F, standard deviation of F, and the sc_v value are given for 30°, 4.096 ms maximum-bandwidth block (BLK), BIR-4, and optimized composite (OPT) pulses. In terms of the width of the distribution of F, the optimized pulse performs slightly better that BIR-4 pulse when ΔB₀ variations are minimal. When no B₀ shimming is applied, the optimized pulse demonstrates superior flip-angle uniformity.

ΔB0	BLK	BIR-4	OPT
SHIM	0.69 ± 0.16(±23%)	1.00 ± 0.09(±9%)	1.03 ± 0.05(±5%)
NO SHIM	0.69 ± 0.16(±23%)	0.83 ± 0.20(±24%)	1.04 ± 0.06(±6%)
