TP and UP were designed using the small\u2010tip\u2010angle approximation for a different composition of up to seven resonance frequencies. TP were computed for each of the 29 \u2010maps, and UPs were calculated using 22 \u2010maps and tested in seven testcases. The performance of the pulses was analyzed using the coefficient of variation (CV) in the 3D heart volumes.
