    Objective analysis of Doppler waveforms can now be performed in real-time using a new system. This technology accurately identifies fetuses at risk of distress as early as 34 weeks gestation.

    Area of Science:

    • Medical Imaging
    • Fetal Medicine
    • Ultrasound Technology

    Background:

    • Objective analysis of Doppler waveforms is crucial for fetal health assessment.
    • Real-time waveform analysis has been a significant limitation in clinical practice.
    • Duplex ultrasound scanners are standard tools in obstetric care.

    Purpose of the Study:

    • To describe a novel real-time data analysis and collection system for duplex ultrasound.
    • To demonstrate the system's capability in providing objective Doppler waveform measures.
    • To evaluate the system's accuracy in identifying fetuses at risk of distress.

    Main Methods:

    • Development of a real-time data analysis and collection system integrated with a duplex scanner.
    • Utilizing the system to obtain objective Doppler waveform shape measures during fetal investigations.
