This study introduces a new system for analyzing echocardiographic images to assess cardiac function. The automated software enhances objectivity and accuracy in calculating heart parameters from ventricular wall motion and shape.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Echocardiography is crucial for assessing cardiac function, relying on parameters like ventricular wall motion and heart wall thickness.
  • Manual analysis of echocardiographic sequences is subjective and lacks reproducibility.
  • Automated image analysis offers objectivity and repeatability for precise cardiac parameter calculation.

Purpose of the Study:

  • To present a system and software for interactive echocardiographic image analysis and visualization.
  • To introduce a novel technique for contour detection based on anisotropic diffusion.
  • To enable objective and repeatable calculation of cardiac function parameters.

Main Methods:

  • Development of a system and software package for echocardiographic image analysis.
