Abstract:
1. A method for determining the location and orientation of a tracking device in relation to a transcranial magnetic stimulation (“TMS”) induction coil device when the tracking device is attached to the TMS coil device for performing navigated brain stimulation, the method comprising: providing a TMS coil device comprising: detecting the locations of the reference point and two or more reflective elements of the tracking device; generating an actual reference coordinate frame for the TMS coil device based on the detected locations of the reference point and the two or more elements of the tracking device, computing an actual location and orientation of the tracking device in relation to the coil windings in the casing based on the actual reference coordinate frame; and adjusting tracking device calibration data used to perform navigated brain stimulation with the TMS coil device including the attached tracking device if a variance exists between an expected and the actual location and orientation of the tracking device in relation to the coil windings, wherein the calibration data is a based on the expected location and orientation of the attached tracking device in relation to the coil windings.
