Area of Science:

  • Cardiology
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Echocardiography is a key tool for cardiac function assessment.
  • Analyzing left ventricular (LV) function is crucial for diagnosing heart conditions.
  • Three-dimensional (3D) analysis offers enhanced insights into cardiac structures.

Purpose of the Study:

  • To develop an automated image processing system for cardiac function analysis using echocardiograms.
  • To enable 3D visualization of the left ventricular myocardium.
  • To investigate the utility of 3D LV wall thickness analysis in identifying pathophysiological changes in ischemic heart disease.

Main Methods:

  • Echocardiograms (apical long axis view) were acquired.
  • Images were transferred to a microcomputer system for processing.
