A deconvolution approach, based on a multi-tensor model, is presented
to solve fiber crossing in diffusion MRI. In order to provide a
direct physical interpretation of the signal generation process,
we re-wrote the classical multitensor ensor model, identifying a
significant scalar parameter &to characterize the deconvolution
process. Simulations show that, in presence of noise, the method
is able to correctly separate fiber crossing. Application on in-vivo
data highlights the ability of our approach to distinguish more
than two fibers within the same voxel, suggesting its application
in fiber tracking or connectivity studies even of complex brain
structures.
