“…Several approaches (Duan et al (2007); Elen et al (2008); Kawagishi (2008); Abe et al (2008); Wang et al (2010); Andrade et al (2011)) have been proposed to extend 2D speckle tracking techniques to 3D with the objective of recovering myocardial motion from a 3D US image sequence. Duan et al (2007) used an optical flow technique to quantify myocardial motion but limited their validation to simulated US data.…”

“…Earlier work by the same authors (Abe et al (2008)) on 3D speckle tracking only reported strain quantification results on a synthetic left ventricle (LV) model. Andrade et al (2011) used 3D speckle tracking to quantify LV twist in 50 patients and highlighted statistical differences between 2D and 3D rotation measurements without looking at strain. Finally, Wang et al (2010) recently proposed an unified Bayesian framework fusing multiple features (speckle patterns, border detection, intensity gradient and motion prediction) to recover 3D motion and strain.…”

This paper presents a new registration algorithm, called Temporal Diffeomorphic Free Form Deformation (TDFFD), and its application to motion and strain quantification from a sequence of 3D ultrasound (US) images. The originality of our approach resides in enforcing time consistency by representing the 4D velocity field as the sum of continuous spatiotemporal B-Spline kernels. The spatiotemporal displacement field is then recovered through forward Eulerian integration of the non-stationary velocity field. The strain tensor is computed locally using the spatial derivatives of the reconstructed displacement field. The energy functional considered in this paper weighs two terms: the image similarity and a regularization term. The image similarity metric is the sum of squared differences between the intensities of each frame and a reference one. Any frame in the sequence can be chosen as reference. The regularization term is based on the incompressibility of myocardial tissue. TDFFD was compared to pairwise 3D FFD and 3D+t FFD, both on displacement and velocity fields, on a set of synthetic 3D US images with different noise levels. TDFFD showed increased robustness to noise compared to these two state-of-the-art algorithms. TDFFD also proved to be more resistant to a reduced temporal resolution when decimating this synthetic sequence. Finally, this synthetic dataset was used to determine optimal settings of the TDFFD algorithm. Subsequently, TDFFD was applied to a database of cardiac 3D US images of the left ventricle acquired from 9 healthy volunteers and 13 patients treated by Cardiac Resynchronization Therapy (CRT). On healthy cases, uniform strain patterns were observed over all myocardial segments, as physiologically expected. On all CRT patients, the improvement in synchrony of regional longitudinal strain correlated with CRT clinical outcome as quantified by the reduction of end-systolic left ventricular volume at follow-up (6 and 12 months), showing the potential of the proposed algorithm for the assessment of CRT.

“…3DSTE is also able to quantify regional and global LV myocardial deformation by strain analysis from a single data aquisition (31,65,66). 3DSTE is a non-invasive tool for quantification of rotational and twist LV mechanics, as well (67)(68)(69). Several calculated dyssynchrony parameters of the LV have been demonstrated by different authors (70)(71)(72).…”

Left ventricular twist: comparison between two- and three-dimensional speckle-tracking echocardiography in healthy volunteers

Abstract: 3DSTE is feasible to assess LV twist deformation. Whereas further investigations using 3DSTE are needed to validate this promising technology, comparing 2DSTE and 3DSTE should be done with caution, as values for peak LV twist differ.
