EMSE® Suite is a software toolkit consisting of 6 modules. The modules may be purchased separately, or as a bundle. Taken together, EMSE® Suite supports the key steps required to combine electrophysiological data (like EEG and MEG) with image data (like CT or MRI) for multimodal dynamic functional imaging. Taken separately, individual modules may be used by customers who wish only a subset of the complete functionality (e.g. EEG time series analysis and display). EMSE® Suite runs under the Microsoft Windows family of operating systems as well as Linux, on Intel- compatible processors.



When used together with Polhemus™ digitizing hardware, LOCATOR allows you to measure accurately electrode locations an external head shape in 3 dimensions. These data may then be used for MRI coregistration and more accurate source estimation. LOCATOR currently supports three Polhemus products: ISOTRAK, FASTRAK, and PATRIOT.


Data Editor

The EMSE Suite DATA EDITOR module may be used as a stand-alone program to view, analyze, filter and transform EEG and MEG time series data, and to select intervals or events for further analysis, including topographic mapping, spatial components analysis and wavelet decomposition.


Source Estimator

EMSE Suite SOURCE ESTIMATOR 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.


MR Viewer

MR VIEWER 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 Processor

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 headshape modeling and cortical surface restriction.



Use VISUALIZER to obtain and view 3D rendered images, combining data from several modalities, including topographic mapping, MRI data and electromagnetic source analysis.
