DINE: Distance Is Not Enough - Learning Global Deformation Priors for Robust Soft-Tissue Point Cloud Registration

DINE is applied to two registration backbones, Robust-DefReg and DefTransNet, using a two-stage strategy: a first-stage model is trained with Chamfer distance, its predicted deformation fields are used to estimate a prior, and the model is then refined with a combined distance and negative log-prior objective.

Fast and robust q-space trajectory imaging using voxel-wise multilayer perceptrons for parameter estimation.

It is concluded that a simple MLP can provide high-quality QTI parameter estimates from short tensor-valued diffusion acquisitions, which enables five-minute, high-resolution QTI and may encourage further clinical studies of markers such as microscopic fractional anisotropy.

Constrained estimation of rotational invariants of the cumulant expansion (RICE) for rapid tensor-valued diffusion MRI

Fast dMRI protocols for obtaining rotational invariants of the cumulant expansion were paired with constrained weighted linear least squares (CWLLS) to stabilize the more fragile WLLS fit, yielding high-quality parameter maps at an online-ready computational cost.
