a Global Descriptor of Cardiac Motion from a Large Cohort of 1000+ Normal Subjects
Fig. 1. The flowchart consists of motion tracking, spatial normalisation, descriptor learning and classification. 2 Methods Prior to the learning of a motion descriptor, we first estimate motion from cine…
Component Analysis for the Classification of Cardiac Motion Abnormalities Based on Echocardiographic Strain and Strain Rate Imaging
) with a GE VingMed Vivid7 equipped with a 2.5 MHz transducer. For each subject, data were acquired in the apical 2-, 3- and 4-chamber views with optimization of the…
