Quantitative visualization of induced current density by the electrical stimulation current inside the anisotropic brain region may play an important role to understand the neuro-modulatory effect during transcranial direct current stimulation (tDCS). For ensuring the clinical applications, precise approaches are required to understand the exact responses inside the human body subject to an injected currents, In this study, we reconstruct current density distribution inside the in vivo canine brain region by combing the directional information obtained from a DTI-MRI scan and the z-component of the magnetic flux density data using MREIT technique.
