Abstract

This paper presents a modified microwave radio-thermometer (MRTM) with material characteristic estimator and multiple temperature conversion tables to measure subcutaneous temperature of a living body This estimator provides a temperature retrieval unit with the data of material characteristics such as permittivity, conductivity, thickness and geometry of the living body. The temperature retrieval unit with multiple temperature conversion tables can select one of the tables and computes temperature value corresponding to measured radiation power. In the experiments, it was shown that the MRTM could reduce measurement errors of about $0.82^{\circ}C\;to\;7.68^{\circ}C$ for the cases of distilled water and mixed liquid at the temperature of $37^{\circ}C$.

본 논문은 생체의 내부 온도를 측정하기 위해서 매질 특성 추정기와 다중 온도 변환표를 갖는 수정된 마이크로파 라디오-써모미터(modified microwave radio-thermometer, MRTM)를 제안한다. 매질 특성 추정기는 생체의 유전을, 도전을, 두께, 형태와 같은 매질의 특성에 대한 데이터를 온도 검색 장치에 전달한다. 다중 온도 변환표를 갖는 온도 검색 장치는 이 변환표들 중 하나를 선택하여 측정된 방사 전력에 해당하는 온도값을 계산한다. 실험에서 MRTM은 $37^{\circ}C$의 온도에서 증류수와 혼합 용액에 대해서 $0.82\~7.68^{\circ}C$까지의 측정 오차를 줄일 수 있었다.
