Description

Fit diffusion weighted imaging data with the ball and stick model.

Notes

Fit diffusion weighted imaging data with the ball and stick model.Fits the Behrens ball and stick model to diffusion-weighted data. The model is S(g, b) = S_0 (f \exp[-b d (-g^T v)^2] + [1-f] \exp[-b d]), where S(g,b) is the DW signal along gradient direction g with b-value b, d is a diffusion coefficient, v is the orientation of anisotropic diffusion, and f is a mixing parameter (0 <= f <= 1)..
