3D harmonic phase tracking with anatomical regularization
We added an original regularization framework defined in an anatomical space of coordinates to HARP tracking. Myocardial incompressibility was integrated as a soft constraint aims at correcting the radial strain. Regularization parameters were adjusted on synthetic data. On volunteer data, our method was found to be as accurate as the start-of-art methods. On clinical data, reduced deformation values were found inside infarcted segments. HARP and Monogenic phases were compared on synthetic data. Yet no significant differences were found between them.
