Parallelizing the Diffusion Model for Breast CT Image Reconstruction from Sparse Cone-beam Projections
RPI ID: 2023-078-301 Innovation Summary: This technology introduces a tomographic image reconstruction system that leverages parallel denoising diffusion probabilistic models (DDPMs) to recover high-quality images from sparse projection data. The system uses a probabilistic framework to iteratively refine image estimates, enabling accurate reconstructions...
