Patriot

The Polhemus PATRIOT is a cost-effective, full 6-degree-of-freedom (6DOF) motion tracking system designed for applications requiring up to two sensors. Utilizing proprietary AC electromagnetic technology, PATRIOT delivers precise position and orientation tracking without the need for line-of-sight, making it ideal for EEG electrode localization tasks.

When combined with the Locator module from EMSE Software, PATRIOT becomes a powerful tool for digitizing EEG electrode positions relative to anatomical landmarks. This integration facilitates accurate co-registration with MRI data, enhancing source localization and individualized head modeling.

EEG Electrode Co-Registration with Locator (EMSE)

Accurate mapping of EEG electrode positions is crucial for effective source localization and integration with neuroimaging data. The PATRIOT system, in conjunction with the Locator software module from EMSE, offers a streamlined solution for this process:

• Digitize Electrode Positions: Capture precise 3D coordinates of EEG electrodes using a stylus probe, ensuring accurate alignment with anatomical references.
• Map Fiducials and Head Shape: Record additional landmarks such as the nasion and preauricular points, as well as optional scalp contours, to aid in co-registration with MRI or standard brain templates.
• Real-Time Visualization and Export: Locator provides immediate visual feedback during acquisition and supports data export to major EEG analysis platforms.
• Seamless Integration: The PATRIOT system connects easily via USB, and its compatibility with Locator ensures a user-friendly experience with preconfigured templates for common EEG cap layouts.

This setup is particularly beneficial for research settings focused on source localization, head model construction, or brain-computer interface development, where spatial accuracy is paramount.
