Title:

Development of Boundary Element Fast Multipole Method for Quasistatic Electromagnetic Modeling of the Brain

 

Abstract:

In this master thesis, several algorithmic improvements of the boundary element fast multipole method (BEM-FMM) for quasistatic electromagnetic modeling of multi-tissue anatomical human models have been suggested and implemented. They include:

  1. Fast solid-angle approach for neighbor potential integral calculations - FMM implementation
  2. Fast cubatures for neighbor potential integral calculations - FMM implementation
  3. Electric-field error cancellation approach for accurate modeling of very large field variations

Along with this, several post/preprocessing improvements of the modeling pipeline have been suggested and implemented. They include:

  1. Automated detection and removal of coincident faces for meshes with duplicated boundaries
  2. Approach for automated volumetric labeling for BEM problems with large surface meshes
  3. Approaches for automated mesh expansion for BEM problems with large surface meshes

The application examples to be presented will include:

  1. Simulation of MIDA head model (with 100+ tissue compartments) for transcranial electrical and magnetic stimulation (TMS, TES)
  2. TMS, TES, and EEG/MEG Modeling toolkits with BEM-FMM
