Abstract :
This paper deals with strain estimation methods used in ultrasound elastography. We recently developed a 2D locally regularized strain estimation technique, which has already been tested with healthy bovine liver samples containing artificial lesions made of agar gel. In this study, we investigated the potential of our method to image the deformation of noninduced (natural) dog tumor lesions during freehand scanning.
