Recent publications in the field of myocardial strain analysis show an increasing interest in phase-based strain quantification, using either the DENSE or the HARP technique. Historically, both techniques arose from a different framework. Both techniques have evolved since their introduction, thereby becoming more similar over time and losing their distinct features. However, in literature, both techniques are still regarded as distinctly different techniques, where a more general treatment of phase-based strain imaging is justified. This abstract discusses differences and similarities between HARP and DENSE in imaging and reconstruction, concluding that DENSE and HARP are actually one and the same technique.
