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

Figure 3

Hyperspectral images of the forearm and palm at different wavelengths at 0 and 10 min of the Mox group. The images of forearm and palm which are at 0 min (a) and 10 min (b) of the Mox group are shown for selected wavelengths from 450, 550, 580, 650, 750, 850, 950, and 1000 nm. In 3(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 3(b), the left shift of color is significant at the corresponding wavelength points compared to 3(a) which indicates that the light reflex intensity is significantly weakened after moxibustion. The color change is most significant at the PC6 (indicated by the arrow) and colors of other areas of hands are also changed.
