From: Myocardial trajectory estimation for 2D cine DENSE MRI using thin plate splines
Circumferential shortening maps dervided using the conventional (a, c) and TPAS (b, d) methods for estimating Langrangian displacment trajectories for a normal volunteer (a, b) and a patient with an anterior myocardial infarction (c.d). The overall strain patterns are similar, however, the TPAS technique results in a smoother strain map with higher strain SNR and without individual pixel dicontinuities.
