Abstract

The invention relates to the technical field of craniocerebral electromagnetic stimulation, and discloses an asymmetric special-shaped coil for craniocerebral electromagnetic stimulation and a craniocerebral electromagnetic stimulation system. The asymmetric special-shaped coil comprises a first coil unit and a second coil unit, the two coil units correspondingly comprise a plurality of wire turns located on the same plane/curved surface, and central side conductors of the two wire turns are arranged right above a central area of an intracranial target area in an up-down overlapping mode. The far-end side conductors of the two multi-circle wire turns are correspondingly arranged above two side areas of the center line of the intracranial target area, so that higher target area stimulation intensity can be formed below the coil according to the characteristic that the currents of the upper and lower center side conductors are in the same direction; meanwhile, through a plane/curved surface bending structure of two multi-circle wire turns, the stimulation intensity of the target area can be further improved, the stimulation range is reduced, and the stimulation depth is improved; and the stimulation sharpness can be flexibly adjusted by virtue of the length asymmetry characteristic of the central side conductor and the far-end side conductors.

Description

technical field [0001] The invention belongs to the technical field of cranial brain electromagnetic stimulation, and in particular relates to an asymmetric special-shaped coil for cranial brain electromagnetic stimulation and a cranial brain electromagnetic stimulation system. Background technique [0002] As one of the important technical means of modern neuroscience, brain electromagnetic stimulation technology is widely used in clinical diagnosis, clinical treatment and scientific research and other fields. In order to accurately and effectively stimulate the intracranial target area and reduce the side effects of stimulation, it is usually necessary to optimize the design of the stimulation coil. [0003] The stimulation coil is used to realize the electromagnetic energy conversion during the stimulation process, and its geometric structure directly affects the spatial distribution of the intracranial focal field. Therefore, the geometric structure optimization of the s...
