Terahertz reflection imaging of hypertrophic scar tissue in Vivo

We use terahertz reflection imaging to measure hypertrophic scar tissue in vivo. The reflected terahertz wave from the scar tissue is significantly different from the reflected wave from surrounding healthy tissue. The absorption coefficient of both areas is calculated and shows that the absorption coefficient of the scar tissue is much lower than the healthy tissue. These data suggest that it could be possible to use in vivo terahertz imaging to quantitatively monitor the effectiveness of wound healing treatments.
