Table 1. Comparison of three dual-band pulses.
| Fourier Pulse | SLR Pulse | Wavelet Pulse | |
|---|---|---|---|
| Peak B1 (μT) | 13.00 | 21.69 | 19.67 |
| Integral of B1 squared (μT2•ms) | 112.0 | 220.9 | 198.0 |
| Real-time SAR during human scan (W/Kg) | 0.7 | 1.1 | 1.0 |
| Relative vector sum across a slice pass-band from Bloch simulation (band 1) | 0.352 | 0.502 | 0.505 |
| Relative vector sum across a slice pass-band from Bloch simulation (band 2) | 0.353 | 0.502 | 0.506 |
| Rejection band ripple at the center carrier frequency | 0.00004% | 0.48% | 0.026% |
Pulse properties are shown for the Fourier, SLR and wavelet-optimized refocusing pulses implemented in a spin echo diffusion EPI pulse sequence.
