Quality assurance of segmental strain values provided by commercial 2-D speckle...
Røsner, Assami; Alessandrini, Martino; Kjønås, Didrik; Mirea, Oana; Queirós, Sandro Filipe Monteiro; D'hooge, JanThe aim of this study was to determine the accuracy and reproducibility of vendor-specific regional strain values by echocardiography using in silico data. Synthetic 2-D ultrasound gray-scale images of the left ventricle (LV) were generated with knowledge of the longitudinal segmental strain values from the underlying electromechanical LV model. Four of five models mimicked transmural infarctions with systolic ...

Bernard, Olivier; Bosch, Johan G.; Heyde, Brecht; Alessandrini, Martino; Barbosa, Daniel Joaquim Cunha; Camarasu-Pop, Sorina; Cervenansky, FredericReal-time 3D Echocardiography (RT3DE) has been proven to be an accurate tool for left ventricular (LV) volume assessment. However, identification of the LV endocardium remains a challenging task, mainly because of the low tissue/blood contrast of the images combined with typical artifacts. Several semi and fully automatic algorithms have been proposed for segmenting the endocardium in RT3DE data in order to ext...
