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

Figure 1

Hyperspectral images of the forearm and palm at different wavelengths at 0 and 10 min of the Con group. Note: the images of forearm and palm which are at normal condition at 0 min (a) and 10 min (b) are shown for selected wavelengths from 450, 550, 580, 650, 750, 850, 950, and 1000 nm. The color scale indicates the degree of light reflex intensity and the intensity from left to right is from weak to strong. The colors of the thenar eminence, antithenar eminence, and 2/3 part in the centre of the palm closely adjacent to antithenar eminence are darkest and the light reflex is strongest. The small part of the centre of the palm adjacent to thenar eminence is lighter and the light reflex is weaker. There is no significant change for the color distribution of the spectral images of PC6 and other areas on the hand between 0 min (a) and 10 min (b).
