Effectiveness of using the reference frame in SP-HR tracking. Magnitude of displacement in the myocardium achieved (a) by SP-HR tracking successively from the first to last time frames and (b) by tracking first from the first time frame to the reference time frame and then from the reference time frame to the last time frame. The colormap is the same as in Fig. 9. The computed (c) x and (d) y displacement components between the first and last image frame for a point near the LV boundary and a (more interior) neighboring point.
