Selective time-reversal pulses for NMR imaging.

Using a nonlinear systems approach, a selective time-reversal pulse for multiple-slice-multiple-echo NMR imaging sequences has been developed. The results of both computer simulation and experiments on a 1.5 T imaging system demonstrate the markedly improved selectivity of the pulse compared to conventional time-reversal pulses.
