The accuracy of spine reconstruction with SCPs
| Reference | Validation | User input | Complexity | Mean error (mm) | Max. error (mm) |
|---|---|---|---|---|---|
| Aubin et al. (1997) [5] | 3D scanner (±0.1 mm) | 18 pt/v (SCP) | High | 2.6 ± 2.4 | – |
| Delorme et al. (2003) [16] | CT (±0.1 mm) | 12 pt/v (SCP) | High | 3.3 ± 3.8 | 7.2 |
| Humbert et al. (2009) [9] | CT (±0.1 mm) | 2 splines/patient | Low | 1.3 ± 3.6 | 4.6 |
| Zhang et al. (2013) [11] | SCP (1.21 ± 1.4 mm) | Contour matching | Medium | 2.7 ± 1.7 | 5.6 |
| Proposed work | Back projection | 6 pt/v (SCP) + orientation | Medium | 2.4 ± 2.5 | 4.6 |
