NINscan, a second generation aNIRS device, designed to minimize motion artifacts. This system has 1. four optical channels via a dual wavelength light emitting diode (LED) source, and two photodiode detectors, 2. one ECG channel, with the three leads shown at right, 3. one active impedance respiration channel, which also uses the ECG leads, and 4. two motion sensing channels, selected from a tri-axial accelerometer.
