Repetitive transcranial magnetic stimulation (rTMS) is evolving for home use. New coil designs, like the eccentric figure-8 and dome-shaped coils, aim to improve therapeutic brain stimulation efficiency and portability.

Area of Science:

Neuroscience
Biomedical Engineering
Medical Devices

Background:

Transcranial magnetic stimulation (TMS) is utilized in both brain function research and treating brain dysfunction.
Current therapeutic TMS systems often require bulky equipment and complex navigation aids.

Purpose of the Study:

To evaluate electric field distribution in the brain using simulations.
To introduce novel coil designs for more accessible home-based repetitive TMS (rTMS).

Main Methods:

Simulations were performed using a coil and a patient-specific brain model derived from MRI data.
Development and assessment of an eccentric figure-8 coil and a dome-shaped coil for therapeutic rTMS.

Main Results:

The eccentric figure-8 coil demonstrates higher efficiency, enabling a smaller driving circuit.

The dome-shaped coil offers broader stimulation coverage and is less sensitive to positioning errors, suitable for home navigation.

Conclusions:

Novel coil designs facilitate the development of more compact and user-friendly rTMS equipment for home therapy.
These advancements address key challenges in making therapeutic brain stimulation more accessible outside clinical settings.
