Products - Overview
 Designed for use by researchers, Source Signal Imaging has developed a
multimodal functional imaging software suite, EMSE Suite. The
modular architecture allows users to purchase only necessary modules, with
the option of incremental expansion. EMSE Suite runs under Windows
95/98/NT4/2000/XP on Intel CPU's.

Locator
When used together with Polhemus digitizing
hardware (PATRIOT, ISOTRAK & FASTRAK), 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.
EEG/MEG Data Editor
EMSE Suite DATA EDITOR 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. Support is included for datasets containing events,
for example evoked response potentials. 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 sophisticated signal processing and statistical
analysis tools. DATA EDITOR takes input in ASCII format or in native mode
from several hardware vendors.
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
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
Processor
Starting with a volumetric dataset from the MR VIEWER base
module, IMAGE PROCESSOR tools support automated 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.
 Visualizer
Use VISUALIZER to obtain and view 3D rendered images,
combining data from several modalities, including topographic mapping, MRI
data and electromagnetic source analysis.
