Controllable Lung Nodule Synthesis via Histogram-Regularized Latent Diffusion Models
Researchers propose a histogram-regularized latent diffusion model that synthesizes realistic lung nodules in 3D CT volumes while accurately preserving intensity distributions characteristic of different nodule subtypes. The method addresses limitations in existing generative approaches by constraining lesion-level intensity profiles during synthesis, enabling improved data augmentation for cancer screening systems and better performance on underrepresented nodule types.
