We present a comprehensive method for reconstruction of fetal dMRI signal using a higher order spherical harmonics representation. We show that intensity correction improves the consistency of the volumetric reconstruction. By applying constrained spherical deconvolution and whole brain tractography to reconstructed fetal dMRI we are able to identify anatomically plausible fiber crossings.
