Abstract

This study aims to understand the application of thermal imaging to detect inflammatory bowel disease. Active inflammation increases tissue temperature, dissipating through different tissue types and fecal matter. In this study, heat conduction in swine gastrointestinal tissue were investigated experimentally and matched to theoretical models to measure the tissue's thermal properties and compute the depth at which inflammation that can be diagnosed by thermography. First, we measured the tissue's thermal conductivity, density, and heat capacitance using thermal transient heat conduction analysis through biomaterials. Then, using thermal conductivity and steady-state analysis of heat diffusion, we estimated the temperature drop through different types of swine intestinal tissue to calculate the detection depth range of thermography. The temperature drop through these experiments shows that heat rise from inflammation in the bowel should be detectable with infrared endoscopy.
