About this paper
Ruirui Huang, Jiacheng Li
MedCondDiff introduces a lightweight, semantically guided diffusion framework for multi-organ medical image segmentation that achieves competitive accuracy on CT and MRI datasets. The model significantly reduces VRAM usage and parameter count compared to other diffusion models, making it trainable on a single GPU.
Key insights
- Semantically guided conditioning is crucial for diffusion models in medical image segmentation to ensure anatomically plausible and accurate outputs, addressing the limitations of unconstrained DDPMs.
- An adapter-based framework with additive feature fusion provides an efficient and effective way to inject domain-specific priors into diffusion models without altering the core architecture, outperforming concatenation.
- Significant reductions in VRAM usage and parameter count for diffusion models can be achieved through careful architectural design and conditioning, enabling practical deployment on single GPUs.
