PlaneCycle: Training-Free 2D-to-3D Lifting of Foundation Models Without Adapters

PlaneCycle introduces a training-free method to convert 2D AI foundation models to 3D without requiring retraining or architectural changes. The technique enables pretrained 2D models like DINOv3 to process 3D volumetric data by cyclically distributing spatial aggregation across orthogonal planes, achieving competitive performance on 3D classification and segmentation tasks.

3D Wavelet-Based Structural Priors for Controlled Diffusion in Whole-Body Low-Dose PET Denoising

Researchers developed WCC-Net, a 3D wavelet-based diffusion model that significantly improves low-dose PET imaging denoising while reducing patient radiation exposure. The AI framework uses frequency-domain structural priors to maintain anatomical accuracy and outperforms existing CNN, GAN, and diffusion baselines across multiple dose levels.
