Reprojection Alignment for Trajectory Perturbation Estimation in Microtomography

Latham, Shane; Kingston, Andrew; Recur, Benoit; Myers, Glenn; Delgado-Friedrichs, Olaf; Sheppard, Adrian


For standard laboratory microtomography systems, acquired radiographs do not always adhere to the strict geometrical assumptions of the reconstruction algorithm. The consequence of this geometrical inconsistency is that the reconstructed tomogram contains motion artifacts, e.g., blurring, streaking, double-edges. To achieve a motion-artifact-free tomographic reconstruction, one must estimate, and subsequently correct for, the per-radiograph experimental geometry parameters. In this paper, we...[Show more]
