Estimation of Cardiac Strain using High Frame Rate Ultrasound

High Frame Rate ultrasound in 2D and 3D allows for the assessment of myocardial contraction with high temporal resolution. This permits the derivation of accurate descriptors of cardiac function such as ventricular contraction times. Current strain measurements are based on image rates of 50-60 frames per second while we describe a methodology to allow strain determination at frame rates above 100 fps and thus overcomes the limited temporal resolution of current strain determinations.
