Multi-angle beam steering may refine 2D strain estimation in animal ultrasound models; leaves open clinical validation in humans.
Does beam steering at multiple angles improve the precision of 2D strain tensor estimation compared to conventional non-steered methods in ultrasound imaging?
Using beam steering at multiple angles in ultrasound imaging allows for more precise estimation of the full 2D strain tensor compared to conventional non-steered methods.
