Key result
Novel 3D echocardiography algorithm reconstructs dynamic LV wall motion vectors from multiplane imaging.
Why the study?
A method to reconstruct a three-dimensional dynamic model of the left ventricle from ultrasonic echocardiography data incorporating wall motion velocities was developed.
The study presents a novel algorithm for 3D dynamic reconstruction of the left ventricle using standard 2D echocardiography views.
Extends 2D echocardiography toward dynamic 3D LV assessment; leaves open validation of accuracy and clinical utility.
A three-dimensional dynamic reconstruction algorithm of the left ventricle of patient’s heart from ultrasonic echocardiography data is developed. The presented algorithm takes into account the longitudinal and transverse velocities of ventricle walls to determine the motion vectors of the ventricular walls. Two longitudinal ultrasonic sections (four-chamber position and two-chamber position) and two transverse ultrasonic sections (at a level of basal segments and at a level of papillary muscles) are used for the reconstruction.
