Table 2.
Vscale voltage gains applied to achieve a 20° flip angle at the transducer focus in the CST simulations, see Eq. 5.
| Vscale values applied to achieve 20° flip at transducer focus | |||
|---|---|---|---|

| |||
| No screen | Solid | Solid (shift, focus) | Mesh |
| 200.95 | 129.03 | 157.47 | 134.29 |
Note: Vscale for the 20° flip angle at the focus of the solid(shift) case is substantially more than it would be if the 20° flip were desired at the center of the birdcage coil as for all the other cases.
