A Correlation Study between Two Adjacent Same-Meridian Acupoints after Laser-Needle Acupuncture with Optical Coherence Tomography and Diffuse Reflectance Spectra

Figure 9

Backscattered light intensities of the LI4 and LI5 acupoints and their nonacupoints before and after the LI4 acupoint was irradiated by a 658 nm laser for 15 minutes and 45 minutes. The top row shows that LI4 acupoint was irradiated for 15 minutes; the bottom row shows that LI4 acupoint was irradiated for 45 minutes: (a) and (e) LI4 acupoint; (b) and (f) LI4 nonacupoint; (c) and (g) LI5 acupoint; (d) and (h) LI5 nonacupoint.
