  Computed Tomography is a powerful imaging technique that allows
non-destructive visualization of the interior of physical objects in different
scientific areas. In traditional reconstruction techniques the object of
interest is mostly considered to be static, which gives artefacts if the object
is moving during the data acquisition. In this paper we present a method that,
given only scan results of multiple successive scans, can estimate the motion
and correct the CT-images for this motion assuming that the motion field is
smooth over the complete domain using optical flow. The proposed method is
validated on simulated scan data. The main contribution is that we show we can
use the optical flow technique from imaging to correct CT-scan images for
motion.
