Optimal Short-Time Acquisition Schemes in High Angular Resolution Diffusion-Weighted Imaging

Figure 1

Profiles of the DOT and the proposed derivations in a single crossing voxel from a real brain in the area of the centrum semiovale. The data is acquired at b=1500s/mm² and 60 gradient directions. For the DOT, the effective diffusion time t is set to 25ms. We observe that the DOT-mODF performs similarly as the DOT reconstructed at R₀=16𝜇m. Additionally, Q-ball and the DOT-ODF show similar diffusion profiles.
