Table 2.

Differences between calculated translational and rotational errors on the ROI with C2 & C3 and the ROI with mandible for patient #1 on each imaging day. Translations are the lengths of the vectorial differences between two error vectors (C2 & C3 – mandible) and rotations are individual component of the difference vectors.
