Creation of the solid brain model

The work is devoted to the description of algorithms for the mathematical processing of MRI images of the human brain. The results of mathematical processing are used to create a mathematical model describing the electromagnetic processes occurring in the brain when exposed to transcranial magnetic stimulation. Transcranial magnetic stimulation is used to treat various neurodegenerative diseases. For the development of models, 3D Slicer Simple Data images were selected, which are freely available in DICOM format. For processing and selection of a three-dimensional surface, step-by-step image processing was performed in the 3D Slicer program. As a result of image processing, the interfaces of media with different electromagnetic properties are distinguished, which makes it possible to develop a solid-state model of the brain of a particular person. The solid-state model describes the geometric parameters of the boundary of the brain media with different electromagnetic properties. The recovered surfaces were exported to the ANSYS SpaceClaim finite element analysis environment.
