Triangulation network personalized multi-coil transcranial magnetic stimulation array and control method thereof

Abstract

The invention discloses a triangulation network personalized multi-coil transcranial magnetic stimulation array and a control method thereof, and belongs to the technical field of transcranial magnetic stimulation. The array comprises a series of hexagonal-prism-shaped connecting nodes and a series of coil segments, wherein the gating direction of the hexagonal-prism-shaped connecting nodes can becontrolled by an upper computer, and the coil segments form an equilateral triangle. According to the triangulation network personalized multi-coil magnetic stimulation array provided by the invention, the coil segments and the nodes form a series of adjacent equilateral triangle stimulation units, and personalized magnetic stimulation is realized by controlling the gating direction and the down-leading direction of the nodes through the upper computer. By utilizing the novel transcranial magnetic stimulation coil array provided by the invention, stimulation can be synchronously carried out on multiple parts of the whole brain domain, and the difference between the novel transcranial magnetic stimulation coil array and a traditional multi-coil magnetic stimulation array is that the shape,size and position of each stimulation unit can be selected. The coil array is flexible and changeable in stimulation form and stimulation position, so that personalized requirements for transcranialmagnetic stimulation can be met.

Description

technical field [0001] The invention relates to the technical field of transcranial magnetic stimulation, in particular to a triangular network personalized multi-coil transcranial magnetic stimulation array and a control method thereof, which can realize personalized transcranial magnetic stimulation. Background technique [0002] Since the magnetic permeability of each part of the head is basically the same, when the magnetic field passes through high-impedance tissues such as skull or scalp, the magnetic field strength will hardly attenuate, and the induced current in brain tissue will not be affected by the existence of high-impedance tissues. intensity, such as figure 1 . In the human brain, the impedance of the scalp, fat and bones is relatively high, and the induced current is proportional to the conductivity of the tissue in the brain, so the intensity of the induced current is small, and it will hardly trigger the excited state of the brain's pain receptors, so it ...

AI Technical Summary

Problems solved by technology

Due to the shape of the circular coil itself, there will be intervals between adjacent coils, which makes it difficult to obtain high-resolution stimulation. Secondly, the size of the stimulation unit of the circular coil is fixed, and the stimulation area and shape cannot be realized. adjustment

Although square coils and straight wire coils solve the resolution problem of circular coils, due to their special shapes, they can only be stimulated in the form of rectangles or lines, and in many cases it is difficult to meet the flexibility of magnetic stimulation.

[0005] In summary, figure 2 Several multi-coil transcranial magnetic stimulation design schemes shown in have problems such as low resolution and shape limitations, which also limit the development of multi-coil transcranial magnetic stimulation technology to a certain extent

In the process of realizing multi-coil transcranial magnetic stimulation, the shape, size and position of the stimulation coil can be adjusted individually according to the needs, which cannot be realized by the traditional multi-coil scheme
