CONFLUX model generates realistic 3D chest CT scans with enhanced clinical control

By PulseAugur Editorial · [3 sources] ·

Researchers have developed CONFLUX, a novel latent diffusion model designed for synthesizing 3D chest CT scans with specific clinical attributes. The model utilizes a 3D variational autoencoder for compression and a rectified-flow transformer for generation, conditioned on detailed radiological metadata. An additional reinforcement learning post-training stage, using group-relative policy optimization, significantly enhances the model's ability to reliably generate requested clinical findings, reducing a substantial portion of the shortfall compared to real scans. The project also includes the release of a large dataset of synthetic chest CTs and an interactive demo. AI

IMPACT Enables more precise and controllable synthesis of medical imaging data for research and training purposes.
