Fast and accurate digitization of 3D sensor positions

The xensor system provides users with the solution for digitizing of 3D electrode positions. xensor takes care of the whole procedure; it records, visualizes and stores positions acquired with a dedicated digitizer. Combined with a step-by-step workflow it enables users to easily visualize electrodes in real-time. The MS-Windows based system operates with a very accurate optical 3D measurement system based on infra-red light

Head shape point generation to achieve highest accuracy

Using only the three fiducial markers for the transformations between the tool-based coordinate system and the MRI coordinate system based on the subject’s MRI and head model can result in high inaccuracies. With xensor your are able to eliminate these inaccuracies by acquiring additional points from the subject’s head surface using the pointer.

Real time tracking with auditory feedback

The position of the digitizer pen is being updated in real time. If the digitizer pen is located at the correct position and this electrode position is digitized, this becomes immediately visible in the 3D view. Also, all previously digitized electrode positions are shown. xensor provides users with a user-friendly assistance during a digitization procedure. By a distinctive sound, sent by the system, the user is able to tell whether digitization is being successful or unsuccessful, without the need to keep track of changes on the screen.

Intuitive digitization with wireless remote control

A dedicated xensor remote control allows the users to switch easily 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. Navigation through the digitization workflow is as easy as that!
