Abstract :
We describe a new resistivity image reconstruction algorithm called J-substitution algorithm. It utilizes internal current density data measured by MRI technique with current injection. Computer simulations show that Magnetic Resonance Electrical Impedance Tomography (MREIT) system using J-substitution algorithm can produce high-resolution static resistivity images of a subject.
