Modular biosignal analysis and multimodal integration suite

EMSE Suite 5.1 is a superb, modular solution for the full range of EEG / MEG and multimodal neuroimaging applications, and the capabilities of the software lend themselves to analysis of ECG / BSPM data as well.  EMSE Suite includes a set of powerful tools for source localization and combination of biosignal results with other imaging modalities, such as MRI, CT, fMRI and PET.  EMSE's modular architecture allows modules to operate independently or as a tightly-integrated suite. 

3D measurement of electrode positions.  When used together with digitizing hardware, Locator allows you to measure accurately electrode locations and external head shape in 3 dimensions. These data may then be used for MRI coregistration and more accurate source estimation.

Preprocessing of EEG / MEG data.  This module may be used as a standalone program to view, analyze, filter and transform EEG and MEG time series data, and to select an interval for further analysis, including topographic mapping.  In addition, the data are directly accessible to Source Estimator module for source analysis, and to the Visualizer module for 3D rendering.  Data Editor includes signal processing and statistical analysis tools.  Data Editor takes input in ASCII format or in native mode from several hardware vendors.

Electromagnetic source estimation.  This module may be used for discrete or distributed dipole source analysis from EEG or MEG data which has been provided by the Data Editor module.  Three shell spherical models or realistic head models (using data from the Image Processor module ) may be used for field calculations.  Source estimates may be output to MR Viewer  for MRI overlay.

Display of MRI and other images in combination with electromagnetic source locations.  Displays magnetic resonance and other images, with specialized features designed for the overlay of electromagnetic source estimation and other functional imaging data.  Seeded dipoles may be obtained (e.g. from fMRI data) for use with Source Estimator.  Image data may be input in raw byte, raw word, ACR/NEMA/DICOM, and several proprietary formats.  MR Viewer is the base module for Image Processor and Visualizer.

Image segmentation, mesh generation and cortical unfolding.  Starting with a volumetric dataset from the MR Viewer base module, Image Processor tools support segmentation, boundary mesh generation, and cortical unfolding. The output may be made available to Visualizer for 3D rendering, or to Source Estimator for realistic head shape modeling and cortical surface restriction.  

3D visualization of EEG, MRI, electromagnetic source locations and other image modalities.  Use this module to obtain and view 3D rendered images, combining data from several modalities, including topographic mapping, MRI data and electromagnetic source analysis.
