Abstract

Current density imaging (CDI) is a relatively new modality of magnetic resonance imaging which enables electric current distribution imaging in conductive object containing water. In the present study, a phantom experiment in a 1.5T MRI scanner was conducted, and the relative error of the obtained total current injection estimation from CDI is 10.62% compared with the actual current injection. The noise arising from hardware and software is analyzed. Several effective techniques to improve CDI images are proposed for future CDI experiments.
