We propose a tractography method, called active cortex tractography (ACT), to overcome gyral bias by enabling fiber streamlines to curve naturally into the cortex. We show that the cortex can play an active role in cortical tractography by affording anatomical knowledge to overcome orientation ambiguities as the streamlines enter the superficial white matter in gyral blades and approach the cortex.
