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.
