Figure 7
Slices from absorption reconstructions, (a) before alignment, and (b) and (c) after alignment with (b) the phase matching method and (c) the optical flow method. The projections have been sorted so that the projection directions of neighboring projections are as close to each other as possible. (d) Rotations and tilts. (e) and (f) Alignment offsets from (e) the phase matching method and (f) the optical flow method. Note how the rotations correlate with changes in Δj, whereas the tilts correlate with changes in Δk. In this case the offsets result from misalignment of the goniometer's rotation axes with the sample center.
