    Area of Science:

    • Medical Imaging
    • Artificial Intelligence
    • Cardiology

    Background:

    • Accurate multiview fetal cardiac ultrasound imaging is crucial for diagnosing fetal congenital heart disease (FCHD).
    • Manual acquisition methods suffer from variability in technical skill and inefficiency.
    • Automated recognition of fetal heart ultrasound views is needed to enhance prenatal diagnostic accuracy and efficiency.

    Purpose of the Study:

    • To develop and validate an automated method for multiview fetal heart ultrasound image recognition and anatomical localization.
    • To improve the accuracy and efficiency of prenatal diagnosis of FCHD.

    Main Methods:

    • Proposed an improved multi-head self-attention (IMSA) mechanism integrated with residual networks.
    • IMSA captures both short- and long-range dependencies across subspaces for precise feature extraction.
    • The method focuses on anatomical structures, reducing the impact of artifacts and noise.

    Main Results:

    • The IMSA-based method demonstrated superior performance in multiview identification and localization.
    • Tested on single-center and 38 multicenter datasets, achieving 3%-15% higher F1 scores than state-of-the-art networks for standard view recognition.
    • The approach effectively utilizes correlations between fetal heart structures for robust view recognition.

    Conclusions:

    • The proposed IMSA method offers a stable and accurate solution for automated multiview fetal cardiac ultrasound analysis.
    • This technology shows significant potential to assist cardiologists in the automatic acquisition of multi-section fetal echocardiography images.
    • The findings contribute to advancing AI applications in prenatal cardiology for improved diagnostic outcomes.
