Özet
Bu çalışmada, farklı akustik parametrelere sahip çok katmanlı düzlemsel ortam için tüm katmanlarda kaynak dağılımı olduğu varsayımı altında termoakustik dalga denkleminin analitik olarak düz ve ters çözümü elde edilmiştir. Çok katmanlı düzlemsel ortam için elde edilen analitik çözüm katmanlı düzlemsel green fonksiyonlarına dayanmaktadır. Çok katmanlı düzlemsel modelleme meme, deri ve karın bölgesi görüntülemelerine uygun bir modellemedir. Elde edilen analitik çözüm ile literatürde var olan homojen ortam varsayımına dayanan çözüm her katmanda noktasal kaynak alınarak sayısal olarak karşılaştırılmıştır.
In this study, we derive analytical forward and inverse solution of thermoacoustic wave equation for inhomogeneous multi-layer planar medium, where the source distribution can exist in all layers with different acoustic parameters. Our solutions are based on methods of the Greens functions for layered planar media. This model is applicable for imaging of tissue structures such as skin, breast and abdominal imaging. We have tested and compared our layered solution and conventional solution for point sources located in a two-layer by using numerical simulations.
