Table 2. Estimated head motion.
Head motion estimates, giving the mean and range (in parentheses) of each metric across subjects. Max displacement is the difference between the two head positions that were farthest from one another during the session. FD = framewise displacement.
| Max translational displacement (mm) | Max rotational displacement (deg) | Mean FD (mm) | |
|---|---|---|---|
| 7T | 2.8 (1.2-4.4) | 2.4 (1.5-3.7) | 0.12 (0.08-0.15) |
| 3T | 1.5 (0.8-2.5) | 2.3 (1.7-3.0) | 0.14 (0.13-0.17) |
