Abstract

Exact knowledge of current distributions induced by transcranial electrical stimulation (TES) in the brain is important for eective clinical use of TES. MRCDI uses MRI to measure the TES-induced magnetic elds for estimating the underlying current ow distributions. The estimation methods can benefit from highly sensitive volume MRCDI measurements at a high spatial resolution. Here, we advanced our 2D spoiled gradient-echo-based MRCDI method for a sparse volume acquisition by using simultaneous-multi-slice (SMS) acquisition. Our SMS strategy demonstrated 25% improvement in noise floors against 2D. We test the performance of our methods by phantom and human in-vivo experiments using cable-loop currents.
