Diffusion-Encoding Gaussian Field for Joint k-q dMRI Reconstruction

Diffusion MRI requires repeated k-space acquisitions over multiple diffusion-encoding directions, making acquisition time dependent on both spatial and angular sampling. Existing joint k-q methods either associate directional parameters with fixed voxels or separate spatial reconstruction from angular completion. Howev...

High-dimensional Embedding Prior for Noisy K-space Domain MRIReconstruction

It is suggested that high-dimensional representation provides a general and model-agnostic mechanism for improving diffusion-based MRI reconstruction in noisy settings, offering a new perspective on robust k-space generative modeling for practical inverse problems.
