Abstract

The invention relates to the field of biomedical engineering, and discloses a brain tissue electromagnetic field analysis method based on a transcranial magnetic stimulator, including: placing the 8-shaped coil of the transcranial magnetic stimulator on the top of the brain; The brain tissue below the site has a planar layered structure; according to the current passed into the figure-of-eight coil and the thickness and conductivity of each layer structure in the brain tissue, the electromagnetic field distribution of each layer structure in the brain tissue is analyzed and obtained. The present invention provides a brain structure electromagnetic field analysis method based on a transcranial magnetic stimulator, which establishes a plane layered model of the brain, considers the influence of layered structure eddy currents, and calculates and analyzes the induced current and magnetic field distribution in each tissue , can more accurately understand the distribution of induced current and magnetic field when different layers of the brain are subjected to magnetic stimulation, so as to provide clinical guidance for the location of current action points and improve the clinical use effect of transcranial magnetic stimulators.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a brain tissue electromagnetic field analysis method based on a transcranial magnetic stimulator. Background technique [0002] The induced current density and magnetic field intensity distribution generated by repeated Transcranial Magnetic Stimulation (rTMS) on the brain tissue are the key factors that determine its stimulation efficacy. How clinicians can quickly understand these principles and master the precise positioning of rTMS is the key to exert its advantages and disadvantages. The key to effectiveness. The safety range and efficacy mechanism of coil stimulation in rTMS precise positioning operation are important contents of clinical teaching, but traditional theoretical teaching cannot vividly explain the advantages of this non-invasive technology. [0003] With the development of magnetic stimulation technology and the continuous deepening and expansion of rese...
