B-mode (far left) and strain images of an in vivo thyroid follicular adenoma using three different speckle tracking methods (middle left: the multi-grid approach; middle right: the lateral-guidance approach; and far right: the axial-guidance approach) with 0.8% frame-average axial strain. There are instances where (a,b) the lateral guidance implementation and (c) the axial guidance had difficulties in predicting tissue motion (arrows in the strain images point to decorrelation noise). The white box in the B-mode image defines the ROI for strain images. The order of images is the same for Movie 3.
