Unpaired medical image translation enhances anatomical fidelity and segmentation accuracy.
Using a diffusion model, the method ensures structural consistency between images from different modalities.
Evaluated on challenging lumbar spine and hip-and-thigh tasks, outperforming existing image translation methods generally.
Supports zero-shot application, allowing models trained on one region to work on unseen areas without retraining.
