Area of Science:

Biomedical Engineering
Neuroscience
Medical Physics

Background:

Transcranial magnetic stimulation (TMS) shows promise for neurological disorders like Alzheimer's and Parkinson's.
Current TMS coils struggle to stimulate deep brain regions effectively due to rapid field decay.
The hippocampus and other deep structures require improved stimulation methods.

Purpose of the Study:

To develop an improved coil array for non-invasive deep brain stimulation.
To investigate the effects of magnetic cores, shielding, and coil geometry on stimulation performance.
To achieve effective stimulation in deep brain areas while maintaining safety.

Main Methods:

Proposed a five-coil array utilizing the cone coil method.
Investigated magnetic core, shielding, and coil size/shape effects.
Employed the finite element method with a realistic human head model for electric field calculations.
Validated simulation results with in vitro (head phantom) and in vivo (pig head) experiments.

Main Results:

Magnetic cores and shielding improved electric field intensity and focality but not decay rate.
Increasing coil size reduced field decay but decreased focality.
An optimized cone coil array design significantly reduced electric field attenuation.
The proposed array achieved stimulation thresholds in deep brain regions within safety limits.

Conclusions:

The optimized five-coil cone array effectively addresses deep brain stimulation challenges in TMS.
This design offers a reliable and efficient solution for non-invasive deep brain magnetic stimulation.
The findings support the potential of this technology for treating neurological disorders.
