Evidence that large vessels do affect near infrared spectroscopy
Scientific Reports, 2022 The influence of large vessels on near infrared spectroscopy (NIRS) measurement is generally considered negligible. Aim of this study is to test the hypothesis that changes in the vessel size, by varying the amount of absorbed NIR light, could profoundly
