Fig. 5. Accuracy of diffusion measures in simulated three crossing tensor data.

Fig. 5.

The tensors were oriented such that they were perpendicular to each other. The tensors had weighting equal to 40%, 34%, and 26% of the signal. Rician noise was added for an SNR = 50. (A) φ/θ angle estimations by Bayesian Multi-tensor Model-selection (BaMM). Open circles represent the results obtained by repeated permutation sampling. Same color legend for all data panels. Permutations that resulted in a single fiber direction are plotted in blue/sky blue (φ/θ). Permutations that resulted in two fibers are plotted in red/pink (φ/θ) and green/olive (φ/θ). Permutations that resulted in three fibers are plotted in purple/lilac (φ/θ), orange/salmon (φ/θ), and teal/cyan (φ/θ). (B) FSL’s BedpostX (BPX). (C) Constant Solid Angle Q-Ball Imaging (CSA-QBI). (D) Constrained Spherical Deconvolution (CSD).
