Non-invasive apparatus for measuring a temperature of a living body and method therefor
First Claim
1. An apparatus for measuring a temperature of a portion of a living body, comprising:
- a signal receiving unit for receiving electromagnetic wave signals emitted from the portion of a living body to be measured;
a signal processing unit for processing the electromagnetic signals input from the signal receiving unit and outputting a radiation power signal;
a medium characteristic measurement unit for measuring a value of a conductivity or a permittivity of the portion of the living body to be measured and for outputting the measured value; and
a temperature conversion unit, including a computer database for storing a plurality of temperature conversion tables with respect to radiation power according to the conductivity or the permittivity of the portion of the living body, for determining a corresponding temperature using the measured value of the conductivity or the permittivity of the portion of the living body and the radiation power signal of the signal processing unit.
