Bu çalışmada antenlerin medikal görüntüleme alanında kullanılması ve doku altında meydana gelen kemik kırıklarının tespit edilmesi üzerinde çalışılmıştır. Kablosuz haberleşmede vazgeçilmez bir öneme sahip olan antenlerin, birçok farklı disiplinlerde kullanım alanı mevcuttur. Bu alanlardan bir taneside medikal alandır. Bu çalışmanın ana konusu antenlerin de medikal alanda kullanılabileceğini göstermektir. Çalışmada lineer (doğrusal) kutuplu antenler kullanılarak, doku altında yer alan kemik kırıklarının bulunması hedeflenmiştir. İlk olarak kurgulanan sistemi klinik alanda uygulamak ve tıbbi görüntüleme sistemini geliştirmek amacıyla; bağlı oldukları durum içerisinde mikrodalga antenin özelliklerinin bilinmesi gerekir [1]. Çalışmada horn anten ve patch antenler kullanılmış ve bu ikisi arasındaki farklar göz önünde bulundurularak, çalışmada en verimli sonucun hangisinden alındığına karar verilmiştir. Elektromanyetik dalgaların insan vücudu ve dokusu üzerinde yüksek yayılım gösterdiği göz önüne alınırsa [2], bu alanda özel antenlerin seçilmesi çok önemlidir. Seçilen horn ve patch antenler kendi aralarında haberleştirilir, birbirlerine aktarılan enerjiler saçılım parametreleriyle tespit edilir ve haberleşen bu iki anten arasına kemikli doku yerleştirilir. Verici antenin yaydığı elektromanyetik dalgalar doku içinden geçerek, alıcı antene ulaşır ve saçılma parametrelerine göre durum değerlendirilmesi yapılır. Kemik kırığı tespitinde, horn antenler ve patch antenler ayrı ayrı denenerek çalışmalar saçılım parametreleri açısından kıyaslanır ve kırık olma durumunda oluşan değişimler tespit edilmiştir.
In this study, it was studied on the use of antennas in the field of medical imaging and the detection of bone fractures occurring under the tissue. The use of antennas, which have an indispensable importance in wireless communication, is available in many different disciplines. One of these areas is the medical field. The main subject of this study is to show that antennas can also be used in the medical field. In the study, using linear (oral) polar antennas, the target was to find bone fractures located under the tissue. First, the established system is to be applied in the clinical field and to improve the medical imaging system; the characteristics of the microwave antenna should be known in their condition. The study used horn antennas and patch antennas and, taking into account the differences between these two, it was determined which of the most efficient results in the study was taken. Considering that electromagnetic waves show a high spread on the human body and tissue [2], the selection of specific antennas in this area is very important. Selected horn and patch antennas are communicated with each other, the energies transmitted to each other are detected by hairstyles and the bone tissue is placed between these two communicating antennas. The electromagnetic waves broadcast by the transmitter antenna pass through the tissue, the receiver reaches the antenna and the situation is assessed according to the distorting parameters. In the detection of bone fractures, horn antennas and patch antennas are tested separately and the studies are compared in terms of hairstyles parameters and the changes occurring in the case of fractures are detected.
In this study, the use of antennas in the medical imaging area and the determination of bone fractures under the tissue were studied. Antennas, which have an important place at the wireless communication point, have also a wide range of uses in many different disciplines. In the same way, working with antennay that provide the opportunity to use in medical field, is the main jubject of this current study. It was aimed to detect bone fractures under the tissue by using linearly polarized antennas. In order to obtain accurate results, implement in the clinical field and develop the medical imaging system, it is necessary to know the properties of the microwave antenna used in the system [1]. Horn and patch antennas were used in this study and it was determined that which one had the most efficient result by considering the difference between these two antennas. Considering the fact of electromagnetic waves also have high propagation over the human body and tissue [2], it is very important to choose the specific antenna for this study. The selected horn and patch antennas are communicated with each other, the energy transmission between them was determined through scattering parameters and a bony tissue is placed between the antennas. The electromagnetic waves radiated from the transmitting antenna pass through the tissue and reach to the receiving antenna and the situation is evaluated according to the scattering parameters. In the detection of bone fractures, horn antennas and patch antennas are tested separately, the performed tests are compared and the changes that took place in case of fracture are determined.
