From: Neonatal non-contact respiratory monitoring based on real-time infrared thermography
IRTR image over neonate's nostrils. Top: Neonatal infrared thermographic image with (a) IRTR signal with δ T = 0.27°C between inspiration and expiration (b) ROI located over the nostrils from which signal in (a) derived. Bottom: Thermal contour plot of the thermography clearly showing the thermal signature over this region at (c) inspiration phase starting and (d) at the expiration phase starting.
