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

Functionality

3D Rendering

• Object surface display with interactive zoom, pan, rotate.
• Multiple surface display with user selected transparency.
• Stereoscopic (red/blue) display option.

Multimodal Imaging

• Overlay scalar map data (e.g. electric potential or magnetic field from DATA EDITOR) as pseudocolor map on head surface (from LOCATOR or IMAGE PROCESSOR).
• Overlay source current density maps (obtained from SOURCE ESTIMATOR) as pseudocolor map on cortical surface (from IMAGE PROCESSOR).
• Overlay source current dipoles (obtained from SOURCE ESTIMATOR) in head and/or brain display

Input/Output

• User Interface. A conventional Microsoft Windows style graphical user interface is used throughout.

Intermodule Communication

• Input. LOCATOR (headshape), DATA EDITOR (scalar maps) SOURCE ESTIMATOR (dipoles, source maps), MR VIEWER (volumetric images), IMAGE PROCESSOR (segmented regions and surfaces).

File I/O

• Input. Files produced by other EMSE suite modules.
• Output. none

Other I/O

• Graphics may be transferred to clipboard for use by other graphics programs or for insertion into word processors.

Documentation

• Printed. User manual, including file formats.
• On-line. User manual and tutorial available as context sensitive hypertext.
