Description
Reza Ghorbani and others present, in a 2026 methods study, a joint framework for rebuilding sped-up three-dimensional diffusion MRI acquired in multiple slabs. Scanning slab by slab speeds the scan but leaves visible boundary seams, and undersampling adds artifacts. Their EPEN method rebuilds the volume and gauges each slab's excitation profile at the same time.
The model treats image and slab profiles as joint unknowns inside a probability frame. A neural network energy prior, trained on clean diffusion images, guides it, plus a term anchoring profiles to a first estimate. Updates alternate between the image, using a majorize-minimize scheme, and the profiles, using regularized least squares. Across speed factors and slab layouts, the method cut boundary artifacts more than standard correction while keeping consistency and contrast. Shorter scan times could follow.
