Abstract

The invention relates to the technical field of brain electromagnetic stimulation, and discloses an asymmetric special-shaped coil for brain electromagnetic stimulation and a brain electromagnetic stimulation system. The coil includes a first coil unit and a second coil unit, the two coil units respectively include multi-turn coils located on the same plane / curved surface, and the central side conductors of the two multi-turn coils are arranged in the cranium in an overlapping manner Just above the center area of ​​the target area, and the distal side conductors of the two multi-turn coils are respectively arranged above the areas on both sides of the center line of the intracranial target area, so that the upper and lower center side conductors can The characteristics of the current in the same direction form a higher target area stimulation intensity under the coil; at the same time, through the plane / curved surface bending structure of two multi-turn coils, the target area stimulation intensity can be further improved, the stimulation range can be reduced, and the stimulation depth can be increased; And the stimulation sharpness can be flexibly adjusted by means of the length asymmetry characteristic of the central side conductor and the distal side conductor.

Description

Technical field [0001] The present invention belongs to the field of craniocerebral electromagnetic stimulation, and in particular to an asymmetric shaped coil and a craniocerebral electromagnetic stimulus system for craniocerebral electromagnetic stimulation. Background technique [0002] As one of the important technical means of modern neuroscience, craniocerebral electromagnetic stimulation technology is widely used in clinical diagnosis, clinical treatment and scientific research. In order to accurately effectively and effective stimulation of intracranial target targets and reduce stimulating side effects, it is often necessary to optimize the stimulation coil. [0003] The stimulation coil is used to achieve electromagnetic energy conversion during the stimulus, and the geometric structure directly affects the spatial distribution of the intracranial focus field, so the geometric structure optimization of the stimulus coil is the core problem in the design of the craniocer...
