Automatic Multi-Stage Classification Model for Fetal Ultrasound Images Based on EfficientNet

This study aims to enhance the accuracy of fetal ultrasound image classification using convolutional neural networks, specifically EfficientNet. The research focuses on data collection, preprocessing, model training, and evaluation at different pregnancy stages: early, midterm, and newborn. EfficientNet showed the best performance, particularly in the newborn stage, demonstrating deep learning's potential to improve classification performance and support clinical workflows.
