Multi-frequency k_T-points refocusing simulations using in vivo $B_1^{+}$ and off-resonance maps. Mean and standard deviation across subjects and slices of (a) flip angle RMSE and (b) integrated RF power, versus number of spokes, for STA and LTA designs. (c) Flip angle RMSE as a function of off-resonance frequency, for CP mode, and LTA-designed single- and multi-frequency k_T-points pulses with 5 and 10 spokes.
