TABLE I.
Simulation results. Focal pressure and positional shift due to skull-array misregistration are reported relative to the ideal case of perfect registration. Results are shown for 230 and 650 kHz. The targeting error is the shift of the anatomical target due to the registration error.
| Skull | Pressure ratio (%) (230 kHz/650 kHz) | Focal shift (mm) (230 kHz/650 kHz) | Targeting error (mm) |
|---|---|---|---|
| 1 | 100/99 | 0.6/0.7 | 0.7 |
| 2 | 99/99 | 0.8/0.9 | 0.8 |
| 3 | 99/99 | 0.9/1.0 | 1.0 |
| 4 | 99/99 | 1.2/1.0 | 1.0 |
| 5(1) | 99/99 | 1.0/1.0 | 1.0 |
| 5(2) | 99/99 | 1.1/1.2 | 1.2 |
| 5(3) | 99/98 | 1.2/1.3 | 1.3 |
