    Area of Science:

    • Biomedical Engineering
    • Medical Imaging
    • Physiological Monitoring

    Background:

    • Accurate temporal correlation between visual data (ciné films) and physiological signals is crucial for comprehensive analysis in various medical fields.
    • Existing methods may lack the flexibility or precision required for simultaneous, real-time data synchronization.

    Purpose of the Study:

    • To describe a novel, versatile ciné marker designed for precise synchronization of ciné films with simultaneous physiological recordings.
    • To present a system that enhances the correlation of visual and physiological data streams.

    Main Methods:

    • Development of a ciné marker system capable of marking specific portions of ciné film.
    • Integration of the marker with simultaneous recording of physiological data (e.g., pressure, electrocardiogram - ECG).
    • Implementation of adjustable marker frequency and duration for flexible data annotation.

    Main Results:

    • The ciné marker successfully synchronizes ciné film frames with concurrent physiological data.
    • The system allows for presettable marking of ciné film segments.
    • Hard-copy tracings of monitored physiological functions are concurrently marked, facilitating direct correlation.

    Conclusions:

    • The described ciné marker offers a versatile and effective solution for correlating ciné films with simultaneous physiological data.
    • This tool enhances the accuracy and ease of analyzing combined visual and physiological recordings in research and clinical settings.
