Abstract

We study images from THz electromagnetic waves reflected in porcine skin samples ex-vivo. The THz images were taken sequentially for a period of time after glycerin was applied to the tissue samples. THz imaging is especially sensitive to the water content of any system. Given that glycerin acts like a de-hydration agent, its concentration and diffusion can be determined observing the THz response. In this work, we process the THz sequential images in order to evaluate the diffusion of the material within the sample. We apply image processing techniques to calculate changes in the area of interaction of glycerin and tissue with respect to time. We also analyze the changes on glycerin concentration as function of time and space using a numerical approach based on a finite-difference algorithm. Obtained results of the diffusion coefficient are in agreement with the reported values in the literature.
