Researchers have developed SSRL-MAR, a novel self-supervised learning framework designed to reduce motion artifacts in 3D brain MRI scans. This method does not require paired clean-corrupted data or explicit motion labels, making it practical for clinical settings. SSRL-MAR employs a three-stage training process involving contrastive learning, a motion artifact synthesis network, and a restoration generator. The framework achieved promising results on both simulated and real-world datasets, significantly improving image quality and anatomical consistency compared to existing methods. AI
