The Polaris® Krios handheld digitizing scanner integrates into OEM neurodiagnostic equipment to measure, identify, and map electrode positions (via attached markers) in EEG, MEG, NIRS, PSG, and ECG tests. The Polaris Krios is based on optical 3D measurement technology that scans up to 256 markers in less than 2 minutes to accuracy within 0.5 mm and repeatability of 0.1 mm. Real-time compensation for data variability ensures only actual markers are measured for mapping and registration purposes.
NDI’s extensive API library provides neurodiagnostic equipment manufacturers with seamless integration and management of this electrode measurement data; for example, recording and naming electrodes against a preset 10-20 electrode placement model. The Krios complements the workflow of existing neurodiagnostic systems by reducing the time and complexity of electrode registration and identification. The electrode setup process, which can be time-consuming and difficult for operators, now takes only minutes.
The Polaris Krios is based on optical measurement technology; the scanner uses light reflected by markers to determine their position coordinates.
The rigid body is transformed from the Krios coordinate system to the subject coordinate system. Using the Krios software, operators can append notes to electrode positions. The final point cloud with all identified marker coordinates, fiducial points, and notes, is saved as a .CSV file for export to the neurofeedback software. The point cloud can then be mapped to a pre-defined electrode configuration within the neurofeedback software.
