The core contribution is a novel semantic feature contrastive learning loss function designed to enhance image quality by evaluating semantic and anatomical similarities across different latent spaces within a U-Net-based architecture. The paper's significance lies in its potential to improve medical imaging quality while minimizing radiation exposure and maintaining computational efficiency, making it a practical advancement in the field.
