3D strain field reconstruction by inversion of dynamical scattering [PDF]

Applied Physics Letters
Strain governs not only the mechanical response of materials but also their electronic, optical, and catalytic properties. For this reason, the measurement of the 3D strain field is crucial for a detailed understanding and for further development of material properties through strain engineering.

Reconstruction of myocardial tissue motion and strain fields from displacement-encoded MR imaging

American Journal of Physiology-Heart and Circulatory Physiology, 2009
A quantitative analysis of myocardial mechanics is fundamental to understanding cardiac function, diagnosis of heart disease, and assessment of therapeutic intervention. Displacement encoding with stimulated-echo (DENSE) magnetic resonance imaging (MRI) technique was developed to track the three-dimensional (3D) displacement vector of discrete ...
