Depiction of functional near-infrared spectroscopy system
Note. There are 10 detectors (blue squares) and 4 Light Emitting Diode light sources (green circles), creating 16 channels. Each channel is the midpoint of the light source-detector pair. The distance between each detector and light source is 25 mm. Locations of unmarked detectors and channels are derived linearly based on geometric properties.
