Computing Cardiac Strain from Variational Optical Flow in Four-Dimensional Echocardiography

Abstract: Myocardial strain is important to assess cardiac function and diagnose cardiovascular disease. Despite the adoption of 4D (volume + time) echocardiography for diagnostic and therapeutic purposes, current clinical practice often relies exclusively on 2D measurements of strain or flow information resulting from Doppler echography. However, strain is a 3D measure of deformation in the radial, circumferential and longitudinal directions and therefore full 3D strain, and in particular out-of-sagittal plane strain c… Show more

“…In the second category of motion estimation techniques, we can find solutions based on optical flow (OF), in which the relative motion of the heart is computed from the velocities of the brightness patterns (examples can be found in Tenbrinck et al (2013), Vyas et al (2014), Gao et al (2015)). Although different authors have proved the feasibility of OF for motion estimation, its main drawback is that it only works with relatively non-complex deformations.…”

Although different authors have proved the feasibility of OF for motion estimation, its main drawback is that it only works for small and relatively non-complex deformations.…”
