Abstract
In this paper we present functional thermal imaging using InfraRed (IR) thermography to measure temperature rise in a skin tissue in transient state after weak cooling. Skin tissue is the multilayer complex biological structure. It can be modelled using thermal-electrical analogy by Foster and/or Cauer networks consisting of thermal resistances and capacitances \(R_{th}-C_{th}\). The proposed methodology allows identifying thermal time constants of a multilayer biomedical structure. The distributions of parameters used for approximation temperature evolution at the upper surface of the skin tissue with psoriasis are presented. They correlate with the inflammation areas of the skin.
