    Quantitative echocardiography offers precise numerical data for clinical decisions. This method utilizes digitalized tracings and computer analysis for detailed cardiac assessments, improving diagnostic accuracy.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Biomedical Engineering

    Context:

    • Echocardiography is traditionally qualitative, limiting precise clinical assessment.
    • Advancements are needed to transition echocardiography towards quantitative analysis.
    • Small, integrated devices can facilitate quantitative echocardiography.

    Purpose:

    • To advocate for and describe a system for quantitative echocardiography.
    • To outline the necessary components: graphic tablet, minicomputer, and electronic reprograph.
    • To detail the digital processing of echocardiographic tracings for numerical output.

    Summary:

    • Digitalizing Time-Motion (TM) technique tracings via a graphic tablet and minicomputer enables quantitative analysis.
    • Results are presented as listings and graphs, analyzing phenomena chronology (e.g., ventricular diameter, valve movement) and inter-phenomenon relationships.
