TMS coil pose map generation method based on electromagnetic simulation calculation

Abstract

The invention belongs to the technical field of cognitive neuroscience, particularly relates to a TMS coil pose map generation method, system and device based on electromagnetic simulation calculation, and aims to solve the problem that an existing TMS coil cannot be quickly and accurately positioned according to an electromagnetic regulation and control effect. The method comprises the following steps: constructing coil array sites and directions on the surface of scalp in an MNI standard space, and matching the coil array sites and directions to an individual brain space to obtain coil array sites and directions of the individual brain space; simulating coil array sites of the individual brain space by a finite element calculation method to obtain brain tissue induced electric field distribution in different coil directions; in combination with brain tissue induced electric field distribution, obtaining an optimal regulation and control effect; and obtaining coil sites and directions corresponding to the optimal regulation and control effect to serve as optimal coil poses of all subareas of the individual brain area, and constructing a TMS pose map of the individual. Rapid and accurate positioning of the TMS coil is realized.

Description

technical field [0001] The invention belongs to the technical field of cognitive neuroscience, and in particular relates to a method, system and equipment for generating a TMS coil pose map based on electromagnetic simulation calculation. Background technique [0002] Brain atlas is an important means to study brain structure and function, and provides a new perspective and research method for the new generation of transcranial magnetic stimulation (Transcranialmagnetic stimulation, TMS) precise neuromodulation technology. At present, TMS mainly uses traditional anatomical brain maps to guide the positioning of TMS coils. Such maps are mostly drawn based on cadaver specimens, which only contain local partition information and lack the description of functional subregions, resulting in limited clinical effects and difficult to achieve TMS in spatial dimensions. The purpose of precise target region localization for neuromodulation. In addition, the position and range of the b...
