Benchmarking Ultrasound Foundation Models for Fetal Plane Classification
Researchers have benchmarked several foundation models (FMs) for fetal plane classification using ultrasound images, aiming to improve diagnostic accuracy in obstetric care. The study compared ultrasound-specific FMs like FetalCLIP and USFM against general computer vision models such as ResNet50 and ViT (DINOv3). FetalCLIP excelled in a linear probing setting, while USFM performed best with full fine-tuning, demonstrating that the choice of pretraining objective significantly impacts transferability and classification performance, especially across different populations.
