The invention belongs to the technical field of cognitive neuroscience, and specifically relates to a TMS coil pose map generation method, system, and device based on electromagnetic simulation calculation, aiming to solve the problem that the existing TMS coil cannot realize fast and accurate positioning according to the electromagnetic control effect question. This method includes constructing the coil array position and direction of the scalp surface in the MNI standard space, and matching to the individual brain space to obtain the coil array position and direction of the individual brain space; using the finite element calculation method to simulate the coil array of the individual brain space location, to obtain the distribution of the induced electric field of brain tissue in different coil directions; combined with the distribution of the induced electric field of brain tissue, to obtain the best regulation effect; to obtain the location and direction of the coil corresponding to the best regulation effect, as the optimal coil for each partition of the individual brain region pose, and construct an individual TMS pose map. The invention realizes fast and precise positioning of the TMS coil.
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...
