Abstract

An accurate motion correction technique is needed to compensate for patient head movement during fMRI procedures. In this paper, a novel, non-intrusive approach to motion correction is discussed. A pattern of structured light is used to measure spatial transformations with a 0.1 mm translational and 1 degree rotational precisions.
