CTI reconstruction framework. (A) SE data acquired at TR₁ and TR₂. (B) Water map W and isotropic conductivity σ_HF map. (C) DTI data before (left) and after (right) pre-processing at all b-values (vertical direction, diffusion encoding direction chosen at random). (D) Estimated extracellular volume fraction χ_e, intra and extracellular water diffusivities d_i and d_e, and extracellular water diffusion tensor D_e. (E) LF conductivity tensor C_LF (top) together with the orientation distribution function (ODF) representation (bottom) in WM and GM. (F) “isotropic equivalent” LF conductivity map ${\mathrm{\sigma }}_{LF}^{iso}$.
