Abstract: This paper presents a comparison between block
matching and elastic registration for the estimation of cardiac
deformation and strain from 3D ultrasound. The comparison
study exploits a new evaluation pipeline recently developed by
the authors. The pipeline generates synthetic sequences that are
extremely similar to real ultrasound recording while the synthetic
cardiac motion is fully controlled by an electro-mechanical model
of the heart. Hereto, five synthetic sequences were generated
corresponding to one healthy heart and four ischemic ones. Elastic
registration returned both the smaller tracking errors and the
most robust strain estimates. Although with limitations, this study
brings further evidence that the new technique might be ready
for extensive clinical testing
