a) Waveforms of hard and quadratic phase-modulated RF pulses with 20 μs duration and flip angle of 5°; b) Magnitude and c) the phase of the excitation profiles of both pulses obtained by Bloch equation simulations and measurements with the pulse sequence in Fig. 3 with dwell time of 5 μs. The experimental data are in good agreement with simulations. The noisy oscillations in b) and c) occur in the region outside the imaged object.
