Knowledge of electromagnetic field distribution parameters such as current density, conductivity, and electric field distribution may play an essential role in understanding DBS therapeutic effects on living tissues. However, until now there has been no experimental method that can measure these field parameters. In this work, we demonstrate that it is possible to quantify electromagnetic field distribution during DBS therapy using magnetic resonance electrical impedance tomography (MREIT).
