Abstract

In hyperthermic oncology, the disease is treated by applying localized heating to the tumor, usually in combination with chemotherapy or radiotherapy. Heating is provided to the tumor from the part where a thin microwave antenna is placed. Here, a coagulated area is produced where cancer cells are killed. In this study, the temperature change, tissue deformation and specific absorption rate (SAR) of the tissue under the microwave effect were calculated. The liver tissue was modeled with a coaxial slot antenna at a frequency of 2.45 GHz and a numerical solution was made in the Comsol program. Result simulations of tissue after 2-4 and 6 minutes were obtained by taking different microwave powers (10-20-30W). It has been seen that the results obtained are compatible with the literature information.

Abstract

Hipertermik onkolojide tümöre genellikle kemoterapi veya radyoterapi ile kombinasyon halinde lokalize ısıtma uygulanarak hastalık tedavi edilir. Tümöre ince bir mikrodalga antenin yerleştirildiği kısımdan ısıtma sağlanır. Burada kanser hücrelerinin öldürüldüğü pıhtılaşmış bir bölge üretilir. Yapılan bu çalışmada mikrodalga etkisi altında dokunun sıcaklık değişimi, doku deformasyonu ve özgül absorpsiyon oranı (SAR) hesaplanmıştır. 2.45 GHz frekansında koaksiyel yuvalı anten ile karaciğer dokusu modellenerek Comsol programında nümerik olarak çözüm yapılmıştır. Farklı mikrodalga güçleri (10-20-30W) alınarak 2-4 ve 6 dakika sonrasına ait dokunun sonuç simülasyonları elde edilmiştir. Elde edilen sonuçların literatür bilgileri ile uyumlu olduğu görülmüştür.
