Building a Three-Dimensional Dynamic Model of Left Cardiac Ventricle from Ultrasonic Data

摘要

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.
