See more details in our article Characterization of the Anisotropic deformation of the right ventricle during open heart surgery published in Journal of Computer Methods in Biomechanics and Biomedical Engineering.
Publication: New insight on the movement and anisotropic deformation of the human heart
Our latest paper describes how In-Vivo DIC measurements compare with standard ultrasound measurements and how the DIC measurements can characterize the anisotropic deformation of the heart much better than the ultrasound method. The results also show that the standard longitudinal strain may not adequately describe the overall function, movement, and behavior of a sick and surgically operated heart.
