AB  - Bu çalışmada bilgisayar ortamında akustik fantom oluşturulmuş ve fantom üzerinde iki farklısıcaklık dağılımı için akustik simülasyon gerçekleştirilmiştir. İki farklı sıcaklık dağılımı içinelde edilen dönüş sinyallerine çapraz korelasyon uygulanarak yerel noktalardaki zamankaymaları hesaplanmıştır. Zaman kayması vektörünün eksenel eğimlerinin doku sabiti ileçarpılmasıyla her noktadaki sıcaklık değişimi hesaplanmıştır. Sıcaklık tahmininde, analizsonucunda bulunan zaman kaymalarının yatay eksene göre eğimlerinin bulunması için geri farkyöntemi ve doğru uydurma yöntemi kullanılmış ve sonuçlar karşılaştırılmıştır. Sıcaklık dağılımıilk durumda doku 37°C’de üniform sıcaklıkta ve ikinci durumda doku merkezi 45°C veetrafında çan eğrisi yaparak azalan şekilde tanımlanmıştır. Sıcaklık ölçümündeki maksimumsapmaların, geri fark yönteminde 1.99°C, doğru uydurma yönteminde 0.75°C olduğu vekullanılan modelin tek boyutlu uygulamada yeterli olduğu görülmüştür. Bu çalışma ile birlikteileride yapılacak çok boyutlu simülasyon ve deneysel çalışmalar için taban oluşturulmuştur.

N2  - In study, virtual acoustic phantom was created and acoustic simulation was performed for twodifferent temperature distributions. Local time-shifts were calculated by applying crosscorrelation to ultrasonic signals obtained from simulation results. The temperature distributionwas estimated by multiplying the axial slopes of the time shift vector by the tissue constant. Inthe temperature estimation, the back difference method and the linear fitting were used to findthe slopes of the time shifts, and the results of two methods were compared. In study, the firsttemperature distribution, defines the tissue is uniform at 37°C, and in the second temperaturedistribution, the temperature is reaching 45°C in the center of tissue in the shape of Gaussiancurve. The maximum deviation in the temperature estimation were found 1.99°C in the backdifference method and 0.75°C in the linear fitting method. Study shows that, time-shift basedtemperature estimation is successful in on one-dimensional application. Thus, basis for futuremultidimensional simulation and experimental studies has been established.
