Abstract

The nonlinearity of the parameter relations for the Shinnar–Le Roux RF pulse design algorithm has induced to performa classification based on the features of the slice profile dueto the RF pulse. In the present paper a generalization ofthe relation between the ripple amplitudes of the SLRBpolynomial and those of the slice profile is given. It allows generation of RF pulses with better slice profiles and slightly reduced energy, avoiding anya prioriclassification. The effect of our estimation has been shown by generating several pulses by generalized estimation ofBpolynomial ripples. In addition, their behavior has been compared to that of analogous pulses generated by means of the classification just mentioned.
