BESA
From Anatomy to Source Localization – Seamlessly Aligned

BESA MRI is a dedicated software solution for transforming anatomical MRI data into precise head models for EEG/MEG source analysis. By bridging the gap between structural imaging and functional localization, BESA MRI empowers researchers and clinicians to enhance the accuracy and interpretability of their neurophysiological data.

With its intuitive workflow and tight integration with BESA Research, the software provides a complete pipeline for individual head modeling—from MRI import, co-registration, and segmentation to 3D visualization and export. Whether you're working with epilepsy patients, conducting cognitive research, or simply striving for the best possible source localization, BESA MRI is your tool for anatomically-informed analysis.

Software Features

  • Automatic MRI Segmentation
    Create high-resolution realistic head models (BEM/FEM) through robust segmentation of scalp, skull, CSF, and brain tissue.
  • Integrated Co-Registration Workflow
    Align EEG/MEG electrode positions or fiducials with the MRI coordinate system using interactive tools or automated templates.
  • Surface and Volume Head Models
    Generate boundary element (BEM) or finite element (FEM) models for individual or template-based localization.
  • MRI-to-EEG/MEG Fusion
    Combine anatomical data with EEG/MEG recordings for accurate source localization in BESA Research.
  • Visualization & Reporting
    View, annotate, and export 3D brain, head, and electrode models with publication-ready visuals.
  • Flexible Data Handling
    Compatible with DICOM and ANALYZE/NIfTI file formats for easy MRI import.
  • Ideal for Clinical & Research Use
    Supports patient-specific head modeling, pre-surgical planning, and advanced neuroscience research.

 

Integrated with BESA Research

BESA MRI works hand-in-hand with BESA Research to provide a seamless workflow from data acquisition to source localization. The co-registered head model can be directly used for dipole fitting, source montages, or distributed source models. This fusion enables better clinical insights and improved accuracy in research protocols.

Why BESA MRI?

High-quality EEG/MEG source analysis depends on the accuracy of the underlying head model. BESA MRI ensures that your analyses are grounded in individual anatomy, giving you the spatial precision you need for confident conclusions—whether you’re localizing epileptic foci or exploring cognitive functions.
