Realization of Magnetic Resonance Current Density Imaging at 3 Tesla

Magnetic Resonance Current Density Imaging (MRCDI) is an imaging modality, which reconstructs electrical current density distribution inside a material by using Magnetic Resonance Imaging (MRI) techniques. In this study, a current source with maximum current injection capability of 224.7mA, under 1kΩ resistive load is used. Experiments are performed with a 2D uniform phantom, in which a current steering insulator is inserted. Magnetic flux density distributions are measured, and current density images are reconstructed. The reconstructed images are in agreement with the reconstructions obtained with simulated measurements.
