简要总结
Laboratory study on healthy volunteers to acquire spectral video data from the tongue and fingers as well as photoplethysmographic data from the forehead, fingers, and earlobes to evaluate and optimize algorithms for imaging photoplethysmography (iPPG) and multispectral imaging (MSI)

结局指标
主要结局
hyperspectral data
时间窗: 16 minutes
false color parameter images, representing the oxygenation in %; the perfusion; the hemoglobin, water, and fat content of tissue in arbitrary units betwenn 0 and 100 from tongues and fingers (imaged areas have to correspond to RGB video data)
multispectral video data
时间窗: 16 minutes
true color video data (10 bit per channel \[red, green, blue\]) from tongues and fingers (imaged areas have to correspond to RGB video data)
plethysmographic wave
时间窗: 5 minutes
numerical value in arbitrary values representing the amount of transmitted/reflected light over time through fingers or earlobes or from the forehead
pulse
时间窗: 5 minutes
frequency in bpm (beats per minute) or Hz (Hertz)
pulsation index
时间窗: 5 minutes
ratio between pulsating and non-pulsating tissue components in %
SpO2
时间窗: 5 minutes
oxygenation of arterial blood in %, measured with a pulse oximeter
RGB video data
时间窗: 16 minutes
true color video data (10 bit per channel \[red, green, blue\]) from tongues and fingers
