Fig 4 — A 2-band SMS Shinnar-LeRoux (SLR) purely amplitude modulated pulse is shown (peak B1 of 21.69 μT) along with the corresponding wavelet decomposition on the left column. The right column shows the amplitude modulated wavelet optimized 2-band SMS pulse yielding the same slice bands as the SLR pulse. The wavelet optimization achieved a peak B1 of 19.67 μT (reduction of 10.7% from the comparable SLR pulse). The lower row shows the wavelet coefficients containing the highest energy. In this example, 3200 time domain points were compressed to 75 wavelet domain coefficients.
