Transcranial magnetic stimulation (TMS) has been used as a non-invasive tool in various neuroscience applications. One of the greatest challenges TMS faces is an exact coil positioning to deliver the pulse to the intended area. In this work, we propose a new method of localizing the TMS stimulation by exploiting the fact that interference of TMS field inside the MR magnet lead to intensity variation of MR images. Our phantom studies showed that origins of the TMS fields could be localized and mapping of the TMS fields can potentially lead to quantification of neurostimulations that the TMS produce.
