Towards estimating cardiac motion using low-rank representation and topology preservation for ultrafast ultrasound data

Abstract: Estimation of the cardiac motion is very important in order to detect heart diseases. This work presents a cardiac motion estimation approach using ultrafast ultrasound data. We optimize a variational framework which has the benefits of combining low-rank data representation with topology preservation. We show through the analysis of experimental results that this combination offers a radical reduction in computational time and noise while ensuring preservation of the anatomical structure of the heart under co… Show more

“…For the third term and Definition 2, we use the topology preservation term that we first proposed in [19], but here we extended it to 3D. This penalization term is based on controlling the Jacobian determinant for preserving the anatomical structure of organs.…”

“…Now, we turn to explaining how we guarantee a diffeomorphic deformation by monitoring the Jacobian determinant | J Φ (x : P) | of the deformation. To do this, we use a function that we first proposed in [21] in which the main difference is the non-trivial optimization process in the three dimensional space. From Eq.…”

“…For the third term and following Definition 16, we use the topology preservation term that we first proposed in [20], which penalizes the Jacobian determinant to preserve the anatomical structure of organs. Unlike works like [195,126,183,234] where topology preservation is not considered, in this work, we demonstrate the relevance of preserving the heart's anatomical structure specially during complex deformations.…”
