Gaussian process regression can turn non-uniform and undersampled diffusion MRI data into diffusion spectrum imaging

9 Nov 2016Jens SjölundAnders EklundEvren ÖzarslanHans Knutsson

We propose to use Gaussian process regression to accurately estimate the diffusion MRI signal at arbitrary locations in q-space. By estimating the signal on a grid, we can do synthetic diffusion spectrum imaging: reconstructing the ensemble averaged propagator (EAP) by an inverse Fourier transform... (read more)
