Abstract
Deep learning, an efficient machine learning method that performs well in multiple domains. It is based on the learning and training of multil ayer neural networks, simulating the neuronal connectivity of the human brain, and realizing the recognition and classification of complex patterns. Deep learning has shown great potential in the medical field, especially in the abnormal detection of fetal ultrasound images. It significantly improves the accuracy and efficiency of detection, alleviates the problem of insufficient data volume through data augmentation technology, and improves the model structure to handle complex images. Deep learning also solves the problem of image noise and artifacts, improving the robustness and adaptability of the model. In terms of multi-classification and fine identification, deep learning can identify different abnormal types, and accurately identify and locate the abnormal areas, optimize the clinical process, improve the quality of diagnosis, and provide patients with more timely and accurate medical services. Although deep learning in fetal ultrasound image abnormal detection face insufficient data quantity, image complexity, model interpretation and privacy risks, but through data enhancement, model structure improvement, visualization technology and the application of differential privacy technology, can meet these challenges, promote the further development of deep learning in this field.
