The NDI Krios is a handheld digitizer system based on 3D position measurement with infrared light. The system is different from the other digitization hardware Compumedics Neuroscan offers, since it uses a scanning technique to capture the positions of multiple electrodes at the same time. This makes this digitizer very fast, accurate and error-proof.
This device is especially suited for those occasions where you need to measure the 3D positions of many electrodes in a cap (i.e. 64, 128 or more). In order to use the NDI Krios digitizer with your caps, you will need to add reflective stickers to the electrodes.
Please note: the NDI Krios digitizer only works with caps, and can not be used to digitize individually placed electrodes.
