Fig. 13.

Illustration of injury susceptibilities using ${\phi }_{\mathit{\text{tract}}}^{\mathit{\text{enhanced}}}$ (top) and ${\phi }_{\mathit{\text{tract}}}^{\mathit{\text{point}}}$ (bottom) for the same pair of athletes. Stars/dashed lines represent tract-wise/average injury thresholds at a 50% probability for concussion. Potentially “injured” tracts (i.e., susceptibilities exceeding the corresponding tract-wise thresholds) are highlighted in gray. Even for the un-concussed athlete, ${\phi }_{\mathit{\text{tract}}}^{\mathit{\text{enhanced}}}$ in CGH-R still exceeded its tract-wise threshold (arrow).
