Indogenous heat measurement method based on infrared skin temperature distribution field

Abstract

The invention discloses an endogenous heat measurement method based on an infrared skin temperature distribution field. The endogenous heat measurement method comprises the following steps: S1, establishing a finite element model; s2, simulating the relationship between the position, temperature and thermophysical property parameters of the in-vivo heat source and the body surface temperature distribution by adopting a finite element analysis method; and S3, burying the developed constant-temperature adjustable heat source in the uniform layered biological tissue body, taking the temperature of the body surface of the tissue and the temperature of each layer of tissue by adopting a human body temperature measurement thermal infrared imager, and analyzing the distribution of temperature fields on the body surface and in the body. Human body skin simulation is carried out through the biological simulation body, the skin temperature of the biological simulation body is shot through the medical thermal infrared imager, data transmission is carried out by establishing a data transmission system, a temperature distribution infrared thermogram is formed, a basis can be provided for diagnosis of an abnormal heat source in the body, and finally simulation and analysis are carried out, so that the diagnosis accuracy of the abnormal heat source in the body is improved. And a theoretical basis and guiding significance can be provided for research on a human body surface temperature distribution characteristic formation mechanism and a heat source inverse problem.

Description

technical field [0001] The invention belongs to the technical field of infrared temperature measurement, and in particular relates to an endogenous heat measurement method based on an infrared skin temperature distribution field. Background technique [0002] Infrared thermal imaging tumor detection has the advantage of being harmless to the human body, and is a good method for breast cancer prevention and screening. However, at present, only the method of comparing the body surface temperature of the tumor area with the body surface temperature of the normal area can be used for diagnosis, and there is a lack of research on the relationship between infrared thermal imaging data and tumor metabolic heat production. In the past 10 years, the most common method is to establish a simple heat transfer model based on the Pennes biological heat transfer equation to study the relationship between the surface temperature distribution of various tissues and the abnormal internal heat...

Problems solved by technology

Due to the low penetration ability of infrared radiation in solids, the temperature field and internal heat source information inside the tissue cannot be accurately grasped simply by taking the distribution image of body surface temperature, and the relationship between physiological processes and clinical manifestations is not yet clear
