Boundary element method with bioheat equation for skin burn injury

Measurement of the perfusion coefficient and thermal parameters of skin tissue using dynamic thermography is presented in this paper. A novel approach based on cold provocation and thermal modelling of skin tissue is presented. The measurement was performed on a person's forearm using a special cooling device equipped with the Peltier module. The proposed method first cools the skin, and then measures the changes of its temperature matching the measurement results with a heat transfer model to estimate the skin perfusion and other thermal parameters. In order to assess correctness of the proposed approach, the uncertainty analysis was performed.

This paper presents a novel screening method based on thermal image classification. The classification uses the thermal parameters of the multilayer structure of the skin tissue as the images' features. These physical thermal parameters are evaluated using the inverse thermal modelling. The thermal process in the tissue was induced by the weak cooling. Temperature rise after cooling was used to recover the unknown thermal parameters including perfusion.

“…In accordance with other skin models [1,6,8,9], the skin is assumed to consist of three layers with different physiological properties: the epidermis (outermost layer of skin), the dermis (intermediate layer), and the subcutaneous fatty layer. These three layers are denoted by R 4 , R 5 and R 6 .…”

“…When analysing burn injury [1,6], it is usual to assume the the temperature at the base of the subcutaneous layer is maintained at the body's core temperature of 37 • C. This is applicable for short time duration events like flash burns. To investigate the thermal properties of a dry suit immersed in icy water for up to 60 minutes, a boundary condition that is applicable to a wider range of environmental conditions is needed.…”

Thermal storage and insulation properties of a diver dry suit incorporating phase change material are investigated. A complete model for the fabric, air-gap, skin system is developed. The numerical results show that the diver dry suit consisting of phase change material and conventional insulating materials provides significantly enhanced thermal protection under cold environmental conditions. A sensitivity analysis investigates how changes in the values of the thickness of air space affect the temperature distribution in the system.
