Strain and strain rate echocardiography

Current Opinion in Cardiology, 2002
Strain and strain rate echocardiography is an emerging technique for assessing myocardial systolic and diastolic function. It is envisioned that this modality could change the quantitative assessment of regional wall motion and improve the accuracy and reproducibility of test readings. Myocardial strain and strain rate can detect inducible ischemia and

Eulerian strain-rate as a rate of logarithmic strain

Mechanics Research Communications, 1995
It is pointed out that the deformation rate or the symmetric part of the velocity gradient can be interpreted as a real time derivative of a strain in a suitable rotating frame. Using principal axes, the authors determine the angular velocity of the frame and apply the general considerations to the special case of simple shear deformation.
