Develop a universal 3D medical latent diffusion framework to generate controllable, high-resolution volumetric medical images across multiple modalities and anatomical regions.
Engineered 3D MedDiffusion with a Patch-Volume Autoencoder using patch-wise encoding and volume-wise decoding, paired with a multi-scale noise estimator.
Trained the framework on large-scale CT and MRI datasets spanning anatomical regions from head to leg at resolutions up to 512×512×512 voxels.
Assessed performance across downstream clinical tasks, including sparse-view CT reconstruction, fast MRI reconstruction, and data augmentation for segmentation and classification.
3D MedDiffusion outperformed existing state-of-the-art generative models in synthesis quality and detail preservation across both CT and MRI modalities.
The framework demonstrated robust generalization, enhancing downstream performance in accelerated MRI, sparse-view CT reconstruction, and segmentation pipelines.
