Özet:

 Although the most preferred treatment methods in cancer treatment are still surgery and chemotherapy, microwave ablation, one of the minimally invasive thermal ablation techniques, is increasingly used in the clinic for patients who cannot afford the risks of these treatment methods. In this study, microwave ablation with a new NiTi ring antenna was performed on a freshly slaughtered beef liver as an Ex Vivo application. Design and optimization was carried out in the CST Microwave studio. Ex Vivo MWA application was carried out at 2.45 GHz, using 50 W microwave power for 5 minutes. The lowest width of the ablation zone formed along the x-axis was 14.58 mm, the highest width was 28.61 mm, the length of the ablation area along the y-axis was 58.032 mm, and the area of the ablation zone was approximately 5.44 cm2. These results show that the proposed NiTi ring antenna has the ability to achieve a sufficient thermal lesion in terms of ablation zone dimensions.

 Kanser tedavisinde en çok tercih edilen tedavi yöntemleri hala cerrahi ameliyat ve kemoterapi olsa da, bu tedavi yöntemlerindeki riskleri kaldıramayacak hastalarda, minimal invaziv termal ablasyon tekniklerinden biri olan mikrodalga ablasyon uygulaması gittikçe artan bir oranda klinikte kullanılmaktadır. Bu çalışmada, Ex Vivo uygulaması olarak yeni kesilmiş bir sığır karaciğerine yeni bir NiTi halka anten ile mikrodalga ablasyon uygulaması gerçekleştirilmiştir. Tasarım ve optimizasyon CST Mikrodalga stüdyoda gerçekleştirilmiştir. Ex Vivo MWA uygulaması, 2.45 GHz de, 50 W mikrodalga gücünün 5 dakika süresince kullanılmasıyla gerçekleştirilmiştir. x ekseni boyunca oluşturulan ablasyon bölgesinin en düşük genişliği 14,58 mm, en yüksek genişliği 28,61 mm, y ekseni boyunca elde edilen ablasyon alanının uzunluğu 58.032 mm ve ablasyon bölgesi alanı ise yaklaşık 5.44 cm2 olarak elde edilmiştir. Elde edilen bu sonuçlar önerilen NiTi halka antenin ablasyon bölgesi boyutları açısından yeterli bir termal lezyonu başarma kabiliyetine sahip olduğunu göstermektedir.
