displays the the singular value order and covariance of the spatiotemporal Casaroti matrix associated with the in vivo thyroid images. (a) displays the singular value decay associated with pre- and post-motion corrected data. The covariance of the pre- and post-motion corrected spatiotemporal matrix is displayed in (c) and (d), respectively. (b) displays the 2D motion vectors associated with the thyroid nodule.
