Abstract :
In this study we investigated multi-frame motion estimation for freehand ultrasound elastography and its application to thyroid tumor imaging. Motion analysis using a technique of compression orientation detection led us to introduce a new parameter based on the angle of estimated motion vectors. We show how our method may improve the quality of the results compared to classical strain images.
