    This study introduces a computer-aided method for ventricular volume measurements. The digital approach demonstrated high accuracy, closely matching manual calculations for ejection fraction and ventricular volumes.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Computational Biology

    Background:

    • Accurate measurement of ventricular volumes is crucial for diagnosing and monitoring cardiac conditions.
    • Traditional manual methods for calculating these volumes can be time-consuming and prone to inter-observer variability.

    Purpose of the Study:

    • To develop and validate a digital computer program for ventricular volume measurements.
    • To compare the accuracy of the automated method against established manual techniques.

    Main Methods:

    • An area-length procedure was implemented using a digital computer for ventricular volume calculations.
    • Results from the digital method were statistically analyzed and compared with those from a manual method using the same formula.

    Main Results:

    • The digital computer program achieved a high correlation index of 0.95 for telediastolic volumes.
    • Correlation indices of 0.99 were observed for telesistolic volumes and ejection fraction when comparing digital and manual methods.

    Conclusions:

    • The developed digital computer program provides a highly accurate and reliable method for ventricular volume measurements.
    • This automated approach offers a significant improvement over manual techniques, enhancing diagnostic precision in cardiology.
