Average Position Error Between SPECT LV Model and Electrophysiology Voltage Map for Different Registration Algorithms, Visual Alignment, or Visual Alignment Followed by Surface Registration
Registration method | ||
Patient | Visual alignment (mm) | Visual alignment plus surface registration (mm) |
1 | 7.1 | 6.0 |
2 | 5.2 | 3.2 |
3 | 4.2 | 3.6 |
4 | 6.1 | 5.0 |
6 | 12.3 | 3.2 |
7 | 6.9 | 4.3 |
8 | 5.2 | 5.1 |
9 | 4.5 | 3.9 |
10 | 6.8 | 4.9 |
Mean ± SD | 6.5 ± 2.4 | 4.4 ± 1.0 |
Difference between 2 methods is statistically significant (P = 0.034).
