title: Polar decomposition radio-frequency current density imaging.
abstract: Polar Decomposition Radio-frequency Current Density Imaging (PD-RFCDI) is an imaging technique that non-invasively measures RF current density components inside a sample using MRI. Previous PD-RFCDI implementations suffer from the strict constraint on the amount of applied current as well as severe interference from the unwanted induced current. This work proposes solutions to both problems which successfully remove the current constraints of PD-RFCDI. Both simulation and experiment were used to verify the validity of PD-RFCDI on a clinical MRI scanner.
