Abstract
Thermal irradiation (TI) is one of the most efficient physical treatments for surface wounds of various etiology (burns, dermatological diseases, oncological wounds, etc.). Computer-controlled directional sources of TI can considerably facilitate efficacy of treatment. Computer control of TI can include mathematical modeling. Computer modeling of TI consists of two parts: the model of the heating device and the model of the human body. The human body model consists of ten segments (30 compartments or three-layer presentations of a segment) which are described by nonlinear equations of the thermal balance of the body. The location of wounds is described in the model by indicating the corresponding compartment. The device is modeled as a system of directional sources of thermal radiation whose radiant flux can be focused anywhere on the surface of the patient's body (including beam movement within a compartment). The TI computer model calculates thermal fluxes received by compartments and thermal exchange between compartments and surroundings and also evaluates common integrated characteristics of the thermal status ~ the body (heat transfer rate, heat content, etc.). The model interface is rather convenient for research purposes.
