Researchers have developed a new method to improve the generation of synthetic medical images using diffusion models. The proposed Fréchet Distance loss (FD-loss) technique fine-tunes these models by aligning statistical features of real and generated images, which helps in capturing complex tumor structures more accurately than standard per-pixel error minimization. When downstream segmentation networks are trained on synthetic data augmented with FD-loss, they show a consistent performance improvement of over 5% in Dice Similarity Coefficient (DSC) for tumor segmentation.
