The estimated orientationally averaged signal using different methods for in vivo data on (a) an axial slice for \(b = 6 \; {\rm ms}/\upmu {\rm m}^2\). (b) in a white matter (left plot) and a gray matter (right plot) voxel for \(b = 6, \; 7.5, \; 9, \; 10.5\) and \(12\,\,{\rm ms}/\upmu {\rm m}^2\) in shell-based methods and \(b = 6, \; 6.1, \; 6.2, \; \ldots , \; 12\,\,{\rm ms}/\upmu {\rm m}^2\) in MAP-based approaches.
