GeoSource™ 3 electrical source imaging packages

The culmination of 25 years of interdisciplinary research, GeoSource 3 Research software leverages

  •  High Density EEG technology
  •  high-resolution MRI imaging
  •  sophisticated electric head modeling
  •  accelerated computing

to create a powerful platform for electrical source imaging for advanced research applications.

Now with individual head models

GeoSource 3 Research electrical source imaging method improves on current ESI methodology by using High Density EEG data and much more realistic head models to define the path of electrical current from the cortex to the scalp.

Higher resolution with High Density EEG data
To provide the best source imaging results, GeoSource 3 software uses High Density EEG data with up to 256 sensors and whole headcoverage.

More realistic head models with 7 different tissue types
Automated software characterizes tissue types — scalp, skull, cerebrospinal fluid, grey matter, white matter, air, and eyeballs — directly from 1-mm MRI data for the most realistic anatomy across the entire head.

More realistic electrical conductivity modeling
using the Finite Difference Method (FDM)
The FDM performs voxel-by-voxel calculations of the electric potentials, maintaining the high resolution geometry of the original MRI image.

Fast and easy step-by-step head model building
A dedicated pipeline software guides you through each step with opportunities to review the model at all stages of construction.

The FDM software is optimized for high-performance computing and is performed using a high-performance GPU compute node (included with Intermediate and Advanced Packages) so that computing time is accelerated from days to minutes.
