Robotic TMS is a highly advanced technique and a unique tool to assure stimulation quality in terms of precision. The combination of a robot, MR-based neuronavigation and focal stimulation makes it is possible to reproduce multiple sessions or ensure identical setups in e.g. multi-center studies.
Modern TMS robots are able to safely readjust to the subject’s head movement and ensure contact between the TMS coil and the subject’s head. Image guided TMS sessions can be planned in advance for fully automatic executions.
In addition to holding the stimulation coil reliably and accurately for target points, TMS robots are also capable of moving along pre-defined paths on the subjects head. With this functionality it is possible to stimulate larger target areas with a focal stimulation coil.
Major considerations and solutions:
Real time force control of the robotic arm.
TMS safety concept with safety restrictions on stimulation intensities and frequencies.
Dedicated workspace and limitation of the robotic arm’s movement range.
Accuracy and reproducibility:
Computer controlled coil positioning with multiple sensors.
Store and recall individually set target points.
Performing complex TMS protocols:
Integration of wireless real-time tracking systems.
TMS stimulator capable of running advanced protocols.
Compatible TMS equipment:
Dedicated lightweight robotic coils with long and highly flexible cables.
