ReBrain: Rebuilding MRI from Sparse CT Slices with Retrieval‑Augmented Diffusion
Can AI fill in the MRI gaps? When MRI isn’t possible, doctors rely on CT—but low‑dose CT can be very sparse. ReBrain is a research system that reconstructs a 3D, MRI‑like brain volume from just a limited set of CT slices. * It uses a diffusion model
