The present study introduces a method to measure the full current density vector field induced by a transcranial direct current stimulation (TDCS) device. Our proposed method uses MRI to measure components of the magnetic field with the phantom/head in different positions. We introduce the theory and demonstrate the method on a current phantom and a human volunteer.
