A Sheet Probability Index from Diffusion Tensor Imaging

  title={A Sheet Probability Index from Diffusion Tensor Imaging},
  author={Michael Ankele and T. Schultz},
A sheet probability index (SPI) has recently been derived from high angular resolution diffusion MRI to quantify the hypothesis that white matter tracts are organized in parallel sheets of interwoven paths. In this work, we derive the DTI-SPI, a variant of the SPI that can be computed from the widely available, simple, and fast diffusion tensor imaging, by considering the normal component of the Lie bracket of the major and medium eigenvector fields. We observe that, despite the fact that DTI… Expand
