ELMA – MRI tissue classification software for setting up electric field FEM simulations in Comsol Multiphysics

ELMA is a free Matlab-based stand-alone program developed by the Neuroengineering group for setting up patient-specific FEM models of DBS in COMSOL Multiphysics. It is used to crop and classify the tissue in preoperative MRI with T1, T2 or proton density weighting. The classification is then converted into electric conductivity matrices for use in the FEM simulations.

A COMSOL app model for DBS simulations is included. It currently requires a COMSOL Multiphysics license to run.
