Controllable Lung Nodule Synthesis via Histogram-Regularized Latent Diffusion Models
Researchers have developed a new latent diffusion model capable of synthesizing realistic lung nodules for CT scans. This model addresses the scarcity of diverse datasets in automated lung cancer screening by generating nodules with controlled intensity distributions, improving visual plausibility and subtype consistency. When used for data augmentation, the synthesized nodules enhance the performance of downstream clinical tasks, particularly for rare nodule subtypes and malignancy classification. AI
