Since skin temperature is influenced by internal and external functions, it is difficult to analyze it quantitatively. We tried, however, quantitative analysis of it with thermography. For convenience of the experiment, we worked out MTI (Mean Temperature Index) on the basis of TI (Thermographic Index) of A. J. Collins. Subjects were 16 normal adults (males) and they were between the age of 19 and 37, mean 25.2 years old. We took thermograms of lower limbs 7 times at the interval of 20 min, when they lay down quiet on the bed more than 2 hours after meal. In order to analyze these thermograms, we divided lower limbs into three parts: thigh, knee and leg. Thermograms are shown in isothermal lines. The results obtained are as follows: 1. Mean values of MTI during experiment indicated the narrow range of distribution. That is; lower Limbs Right 3.87, Left 3.84, Thigh R. 4.08, L. 3.89, Knee R. 3.63, L. 3.59, and Leg R. 3.50, L. 3.47. 2. Skin temperature of lower limbs settled 60 min after lying down on the bed. 3. The period of MTI transition patterns was getting short in order of thigh, knee and leg. 4. The value of MTI decreased in order of thigh, knee and leg. 5. MTI method makes it possible to analyze skint temperature quantitatively, and also to utilize thermography for examining thermal effect.
