Abstract

In this study, the characteristics of the temperature generated by light irradiation, on the surface of a biological tissue with an abnormal tissue part (paraffin) and at the surroundings of the abnormal tissue were studied by numerical and experimental methods. The temperature in the tissue was solved using the computational heat transfer and was compared with the temperature measured with thermocouples. The effects of the light wavelength and the irradiation time on the temperature distribution were analyzed. As a result, the temperature distribution from the irradiation of light in the biological tissue was different when there was an abnormal tissue part. The temperature in the biological tissue with the abnormal tissue part was higher than in a normal tissue.

본 연구에서는 비정상조직(파라핀)을 가진 생체조직에 광을 조사하고 그에 따른 조직의 표면온도와 비정상조직 주위에서의 온도분포를 실험과 해석적 방법을 통해 분석하였다. 파라핀을 이용하여 비정상 조직을 모사한 후 조사하는 광의 파장과 시간을 변화시키면서 조직 주위에서의 온도를 K형 열전대를 사용하여 측정하였다. 또한 전산열전달 기법을 이용하여 해석적으로 조직에 대한 온도분포를 예측하였다. 정상조직과 비정상조직의 주위에서의 온도는 차이가 있었으며, 비정상조직이 있는 경우 표면과 조직 주위의 온도가 높게 나타났다.
