We proposed an improved diffusion MRI-based fiber tractography using functional information. Bold signals are modeled as spatio-temporal correlation tensor and than used to constrain the tractography. This Constrained tracking method can ensure more accurate tracking direction estimation thus benefit more rigid tracking results.
