Abstract

Cardiovascular events are one of the main causes of death in the world. Considering that most of these events are produced by asymptomatic lesions, early and noninvasive analysis and detection of hints for such afflictions are quite desirable. In this work, we study a method known as Lagrangian Speckle Model Estimator (LSME) for assessing the full strain tensor that describes tissue motion between two states during vascular pulse. We then evaluate the results of the LSME method using computer generated images, varying certain mechanical and computational parameters. The strain maps obtained were then assessed, showing percent variation within range of the exact solution. Qualitatively, strain patterns were similar to the analytical solution. Finally, a discussion about further improvements and error causes is carried out.
