Optical positioning system xensor™ system components

EEG electrodes

xensor™ is the time-efficient and straightforward solution for precise and reliable digitization of sensor positions, as for example EEG electrodes. The system’s intuitive and user-friendly workflow in combination with an infraredbased high-accuracy measurement real-time digitization of sensor positions in 3D system enables the user to easily pinpoint, digitize and visualize the positions of EEG electrodes in real-time. Tracking tools: A wireless pointer tool is used for acquiring electrode positions. The position and orientation of the tool is tracked and visualized real-time on a monitor. A head reference tool is affixed on the patient’s head, to allow the tracking of the patient’s head movements. xensor software on a high-performance PC: xensor software is delivered on a high-performance Windows 10 PC for optimized work efficiency. Optical tracking system: The electrode digitizer system is based on the NDI Polaris infrared camera system. The camera sends out infrared light which is reflected by multiple reflective spheres on the tools. This produces highly accurate location information that is used for the digitization of each electrode position. Remote control: xensor comes with a wireless remote control which allows easy switching between different steps in the workflow. Press left or right to go back or proceed with the procedure, choose the upper or lower button to rotate the 3D head model in different directions. Going through the digitization workflow with the remote control is as easy as that!
