Description: Radio current density imaging (RF-CDI) is an imaging technique that measures electrical current density at the Larmor frequency non-invasively utilizing magnetic resonance imaging (MRI). Only a single slice could be imaged using the previous RF-CDI techniques, which limited its potential applications.This thesis presents the first implementation of multi-slice RF-CDI based on the rotating frame imaging technique, for a clinical MRI machine. The noise performance of multi-slice RF-CDI was analyzed and investigated through simulations and experiments. The multi-slice RF-CDI sequence was tested on a standard phantom and radio frequency current density images were acquired on a homogenous cylindrical phantom. Experimental results have shown that the sequence has extended the ability of RF-CDI to image multi-slice RF current density.
