Table 1
Manual estimation of the initial error in mm (i.e., error of the registration given by the neuronavigation system).
| A priori estimation of the registration: initial error in mm | Mean (std) | Expert 1 | Expert 2 | Expert 3 | value |
| Patient 1 | 5.52 (1.15) | 4.31 (1.55) | 5.00 (1.50) | 0.30 | Patient 2 | 8.64 (0.89) | 8.31 (1.24) | 8.76 (1.04) | 0.69 | Patient 3 | 3.56 (1.09) | 4.61 (1.39) | 4.38 (1.13) | 0.13 |
