[A semi-automatic system for the analysis of ecocardiographic tracings (author's transl)]

Area of Science:

• Cardiology
• Biomedical Engineering
• Medical Imaging

Context:

• Echocardiography is a crucial non-invasive imaging technique for assessing cardiac function.
• Accurate quantitative analysis of echocardiographic data is essential for diagnosing and managing cardiovascular diseases.
• Semi-automatic systems can improve the efficiency and reproducibility of echocardiographic analysis.

Purpose:

• To describe a semi-automatic system for the quantitative analysis of left ventricular echocardiographic traces.
• To evaluate the accuracy of filtering, interpolating, and averaging processes in the system.
• To assess the system's capability in calculating ventricular indexes, continuous functions, and mechanical properties.

Summary:

• A semi-automatic system processes echocardiographic traces of the left ventricle using filtering, interpolating, and averaging techniques.
• The system calculates ventricular indexes (stroke volume, ejection fraction, fiber shortening velocity) and continuous functions (ventricular diameter, volume, wall thickness, velocity of cavity dynamics).
• Correlating echocardiographic data with calibrated carotid pulse and brachial pressure allows for calculation of circumferential stress and ventricular compliance.

Impact:

• Provides a tool for more comprehensive and quantitative assessment of left ventricular function.
• Enhances the understanding of cardiac mechanics by integrating imaging and pressure data.
• Offers insights into the advantages and limitations of semi-automatic echocardiographic analysis for clinical applications.
