Coronal views of mean estimated orientations of two fiber compartments for different models (from left to right): The ball & stick model, the RubiX model with orientation conditional priors and the RubiX model with orientation, volume fraction (f s) and diffusivity (d) conditional priors. For all models an ARD prior was employed for f₂. The orientation vectors are superimposed on the f s maps, estimated by each method. A second orientation vector is shown in blue only for voxels where f₂ > 0.05.
