Maximum averaged 10 g SAR and excitation fidelity results of RF pulses designed with different constraints.
| Pulse Design Type |
Unconstrained | Global SAR Constrained |
Fully Constrained |
Fully Constrained, Averaged 10g SAR: 0.5W/kg |
Averaged 10g SAR: 0.5W/kg |
Fully Constrained, Averaged 10g SAR: 0.025W/kg |
|---|---|---|---|---|---|---|
| Maximum Average 10g SAR (W/kg) | 1.18 | 0.82 | 0.64 | 0.45 | 0.45 | 0.02 |
| Predicted Maximum Peak Power (W) | 1088 | 992 | 700 | 700 | 754 | 75 |
| NRMSE | 0.022 | 0.023 | 0.026 | 0.032 | 0.032 | 0.1 |
Lower maximum average 10g SAR results on the designed RF pulses are obtained compared to enforced limits due to the predefined maximum worst-case 10g SAR overestimations during VOP calculations.
