Thermal parameters of biological tissue are important indicators to reveal the capacity of thermal heat transport and heat-carrying and further study of bio-heat transfer mechanisms, and thermal conductivity is one of the basic thermal parameters of biological tissue. This paper achieved a real-time reigning measurement and analysis of thermal conductivity of lean pork, fat, and liver using isothermal heating method: at first, we selected three kinds of biological tissue, each piece of the selection, and put the heat source in the middle position; then, we set five temperature observations which had different distances from the center point, and measured the system power-time curve and the temperature of each point; finally, thermal conductivity data of each point were obtained by the MATLAB processing. The results show that different tissues have different thermal conductivity, and thermal conductivity of lean pork is the largest, followed by liver, and fat minimum; thermal conductivity at different positions within the same tissue are similar. This measurement method and the results have an important significance for developing a deeper study of bio-heat transfer mechanism, the non- destructive temperature reconstruction on tissue, and tumor hyperthermia and so on.
