Researchers have developed a new unsupervised deep learning framework to denoise low-dose computed tomography (CT) liver scans. This method addresses the challenge of using real clinical data, which is often not suitable for direct supervised learning. The framework integrates U-Net for feature extraction, an attention mechanism for fusion, and a residual network, incorporating perceptual loss to enhance medical image characteristics. Experiments demonstrated excellent performance, validated by imaging physicians, meeting clinical needs. AI
