This study introduces a computer system to model the left ventricle using ultrasound images. The system reconstructs 3D cardiac data to estimate key heart parameters during the cardiac cycle.

Area of Science:

  • Medical imaging
  • Biomedical engineering
  • Cardiovascular research

Background:

  • Accurate assessment of left ventricular function is crucial for diagnosing cardiac diseases.
  • Traditional echocardiography methods have limitations in precise volumetric and functional analysis.
  • 3D reconstruction offers enhanced visualization and quantitative analysis of cardiac structures.

Purpose of the Study:

  • To describe a computer-based system for estimating the half-ellipsoid model of the left ventricle.
  • To utilize 2D freehand spatial calibrated echocardiography for 3D cardiac reconstruction.
  • To measure left ventricular parameters during diastole and systole using the fitted model.

Main Methods:

  • Development of a computer system for medical applications.
