[HTML][HTML] Deep learning-based parameter estimation in fetal diffusion-weighted MRI
Diffusion-weighted magnetic resonance imaging (DW-MRI) of fetal brain is challenged by
frequent fetal motion and signal to noise ratio that is much lower than non-fetal imaging. As a …

[HTML][HTML] Learning to estimate the fiber orientation distribution function from diffusion-weighted MRI
… For U f we used n f = 362 , leading to a resolution of 7 . 2 ∘ . In some experiments we
increased n f up to 2500, corresponding to a resolution of 2 . 8 ∘ , but did not observe significant …
