Research on the Noninvasive Measuring Technique of Bio-body's Core Temperature and the Basis to Simplify

Liu Jing; Ren Zepei; Wang Cuncheng(Dept of Thermal Engineering, Tsinghua University , Beijing, 100084)  
Based on Pennes' classical bioheat equation, an equation for direct inferring bio body’s core temperature is derived by using the extending method from a base point. This will make it possible to get local core temperature anywhere in a bio-body without any damage. In Order to increase the measurement range of current instruments to find temperatures inside the body a polynomial interpolating and extrapolating method is introduced , and the temperature information beyond invasive depths can be accquired. Suggestions are made to develop multifunctional biomedical instruments which may measure all thermal properties, body’s core temperature, even could be used for diagnosis and treatment.
