Table 1.
Comparing theoretical and measured values (in brackets) of the efficiency for the coil designs when wound as field and gradient coils.
| Coil | Efficiency as field coil (nT/mA) | Efficiency as gradient coil (nT/m/mA) | Single plane Inductance (μH) |
|---|---|---|---|
| Bx and Gx | 0.74 (0.57 ± 0.01) | 1.20 (1.11 ± 0.02) | 169 (192) |
| By and Gy | 0.74 (0.47 ± 0.02) | 1.20 (0.98 ± 0.02) | 169 (193) |
| Bz and Gz | 3.9 (3.6 ± 0.3) | 4.6 (4.5 ± 0.7) | 379 (385) |
Errors are the standard deviation from the mean of measurements taken across three OPMs spatially separated in z. The single plane inductances are also reported.
