Abstract

A mathematical model has been developed for the numerical analysis of thermal conditions within the human body. The model is based on a numerical calculation of bio-heat equation and a mathematical model of a thermoregulation system. The internal temperatures, heat fluxes, and blood temperatures of all segments are calculated simultaneously. We try to apply the model to clinical diagnosis by using thermography images. This paper describes the fundamental analysis of the calculated results and the experimental results. The calculated results compared rather well with the experimental results in some thermal environmental conditions
