2022年5月1日 · We present validated models of 25 TMS coils for electric field simulations. Models are based on measurements, avoiding use of ambiguous technical coil descriptions. Peak field strength and motor threshold are poorly related to depth and focality. Field strength is more sensitive to details of coil design than depth and focality.

To explore the field characteristics and design tradeoffs of coils for deep transcranial magnetic stimulation (dTMS). We simulated parametrically two dTMS coil designs on a spherical head model using the finite element method, and compare them with ...

2024年8月21日 · In this paper, we developed a novel multi-task deep neural network which simultaneously predicts the optimal coil placement for a given cortical target as well as the associated TMS-induced ...

2021年12月15日 · Transcranial magnetic stimulation (TMS) is a technique employed for the transcranial stimulation of the human brain using a coil positioned on the surface of the head. The coil is driven by pulsed electric currents of several hundred amperes for approximately 50–150 μs to produce transient magnetic fields of approximately 1 T.

2024年2月13日 · To address the requirements of therapeutic TMS coils while mitigating efficiency reduction, we propose a novel TMS coil design methodology with two primary objectives.

2025年3月19日 · Repetitive transcranial magnetic stimulation is used to treat various neuropsychiatric but its considerable power consumption and large size limit its potential for broader utility. Here, the ...

2008年1月24日 · Several complex designs for multiloop coils have been proposed to increase the focality or improve the penetration to deep brain structures. This article describes factors of TMS coil design such as mechanical forces and coil lead wires, cooling systems, materials of construction of coil windings, etc.

2016年12月29日 · In TMS, a time varying magnetic field generated from an electromagnetic coil placed on the scalp is used to induce an electric field inside the brain. TMS coil geometry plays an important role in determining the focality and depth of penetration of the induced electric field responsible for stimulation.

To perform an accurate comparison of 25 commercial TMS coils from four manufacturers, we reconstructed models directly from measurements of their electromagnetic fields and pulse waveforms. We used these models for comparisons of the maximum electric field induced in the cortex, estimated motor threshold, stimulation depth, and focality.

The design of TMS coils determines the electric field pattern that is induced in the brain. Depending on the stimulation target, designs with various degrees of focality and field penetration depth could be desirable.
