EEG DigiTrac 3D Mapping Module

The optional module of 3-D Brain Mapping enables displaying the projection of the map onto a three dimensional head model or brain model. Advanced mathematic algorithms and a wide range of transformations such as: Surface Current Density, Coherence Mapping, Potential Change Velocity, Relative and Absolute Power Spectrum, or Potential Asymmetry Mapping, Dominant Frequency and Centre of Gravity Mapping place our mapping among the world leaders of EEG analysis software.

Displaying isometric maps:
- Maps are projected onto a head or brain model
- Free rotation of a head or brain model
- Map zoom in and zoom out
- Display of a 2D and 3D brain map

Options of a brain map display:
- Isometric displaying maps:2D- and 3D-Mapping
- Potential mapping
- Surface current density mapping (SCD)
- Potential change velocity mapping (time derivative)
- Relative power spectrum mapping %
- Absolute power spectrum mapping % (RMS)
- Potential asymmetry mapping
- Coherence mapping and its phase for leads
- Dominant frequency and centre of gravity mapping
- Preview of the electrode value and selected point of the map
- Automatic adjustment of the color scale
- Mapping with the application of the ear reference electrodes, Goldman electrode (avaraged), Cz, Fz or laplacian
- Display of many maps (from the determined range)
- Application of various value interpolation methods
- Mapping of the skull and the brain model in 3D
- Maps printing in color and in a grayscale
- Displaying of isolines
