B 1 +-insensitive slice-selective pulses constructed from optimized non-selective composite waveforms

Fig. 3: Images acquired at 7 T with a GRE sequence (TR = 5s) using sinc excitations (left) and the composite pulse excitations from Fig. 2 (middle). Line profiles (right) reflect signals from the two pulse types after adjustment for the slice profile differences reported in Fig. 2. Results for both 45° (top row) and 90° (bottom row) pulses are included.
