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

Figure 11

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