ABSTRACT

Mathematicalmodel for heat transfer processes in human layered tissues and a new parametricidentification approach-inverse problem method were adopted in order that the distortionof relative skin temperature due to physiological destruction of an organ in the abdominalcavity and its physical-physiological mechanism might be investigated. By utilizing theabove-mentioned method together with the experimental data on temperature variation in anartificial thermo-focus, this difficult physical medicine problem was settled and thusoojective criteria and interpretation were provided for the infrared thermographydiagnosis.
