Visualizer

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.
