Design of multidimensional radiofrequency pulses in magnetic resonance imaging
… question. The primary challenges are: a) the nonlinearity of the governing Bloch equation, inaccurate treatment of which can cause excitation pattern distortions in the large-tip-angle regime; and b) the long duration of multidimensional RF pulses, which can cause signal loss and excitation …
