Synthetic data generation, particularly using intensity clustering and real image fine-tuning, significantly improves the domain generalization of deep learning models for fetal brain MRI segmentation, outperforming traditional physics-based simulations and achieving comparable results to state-of-the-art methods trained on larger, multi-domain datasets.
AtlasSeg, a novel deep learning model, leverages gestational age-specific atlas priors and a dual-U-Net architecture with multi-scale attentive fusion to significantly improve the accuracy of cortical segmentation in fetal brain MRI, outperforming existing state-of-the-art methods.
