A Pilot Study on Effects of Acupuncture and Moxibustion by Hyperspectral Imaging Technique

Figure 2

Hyperspectral images of the forearm and palm at different wavelengths at 0 and 10 min. Note: the images of forearm and palm which are at 0 min (a) and 10 min (b) of the Acu group are shown for selected wavelengths from 450, 550, 580, 650, 750, 850, 950, and 1000 nm. In (a), there is no significant change for the color distribution of the spectral images of PC6 and other areas on the hands compared to Figure 1(a). According to the color scale, in (b), there is left shift of color at the corresponding wavelength points compared to (a) which indicates that the light reflex intensity is weakened after acupuncture.
