Cardiovascular events are one of the main causes of death in the world. Considering that most of these events areproduced by asymptomatic lesions, early and noninvasive analysis and detection of hints for such afflictions arequite desirable. In this work, we study a method for estimating the full strain tensor for describing tissue motionbetween two states during vascular pulse. We then evaluate the results of the LSME method using computergenerated images, varying certain mechanical and computational parameters. The strain maps obtained arethen assessed qualitatively and quantitatively for a comparison with the exact solution. Also, a discussion aboutfurther improvements and error causes is carried out.
