A dive into fNIRS - from physics to data analysis
Matteo Caffini was born in Mantova, on Aug 24th, 1981. He studied Bioengineering and Physics at Politecnico di Milano and Massachusetts Institute of Technology. He has been working with fNIRS and Medical Imaging since 2003, developing instrumentation, physical models and performing clinical trials. He recentely joined ACN Labs at CIMeC in Rovereto.
Data analysis for functional Near InfraRed Spectroscopy (fNIRS) has evolved in the last twenty years, from well-known saturation-like analysis to modern Diffuse Optical Tomography (DOT). Moreover, anatomically informed fNIRS can now complement the classical fNIRS analysis and help the cortical localization of the brain signals. In this presentation, the physical principles of fNIRS and fNIRS instrumentation will be first discussed. Then, we will fly over data analysis of functional information, in particular discussing time analysis, depth analysis and space analysis of fNIRS data.
