<unk>  <unk>  is an extension of magnetic resonance imaging (MRI), developed at the University of Toronto. It employs two techniques for spatially mapping electric<unk>  pathways through tissue: * LF-CDI, low-frequency<unk> , the original implementation developed at the University of Toronto. In this technique, low frequency (LF) electric<unk> s are injected into the tissue. These<unk> s generate magnetic fields, which are then measured using MRI techniques. The<unk>  pathways are then computed and spatially mapped. * RF-CDI, radio frequency<unk> , a rotating frame of reference version of LF-CDI. This allows measurement of a single component of<unk><unk> , without requiring subject rotation. The high frequency<unk>  that is injected into tissue also does not cause the muscle twitching often encountered using LF-CDI, allowing in-vivo measurements on human subjects.
