In contrast to EEG, thanks to the good spatial resolution of fNIRS, precise localization of optodes on the head can make a major difference in the outcome and repeatability of fNIRS studies. In recent years, several publications have shown the viability and benefit of using photogrammetry to determine optode placement quickly and precisely relative to landmarks on the head. The Intelligent Biomedical Sensing (IBS) Lab has implemented such a solution into their novel python-based toolbox “Cedalion”, which is available open source to the research community. In this workshop Dr. Alexander von Lühmann and Dr. Eike Middell will demonstrate the typical workflow to help users to adopt or reproduce their method.
