For the education of X-ray imaging, having a detailed knowledge on the interaction of radiation with matter is very important. Also the generation and detection concepts of the X-ray have to be grasped well. Sometimes it is not easy to visualize the interactions and assess the scheme in quantum physics level for the medical doctors and the engineers who have not studied on the modern physics in an appropriate level. This thesis aims to visualize these interactions, X-ray generation and detection, and computerized tomographic imaging. With these simulations, the user can 1) observe and analyze which type of interaction occurs under which condition, 2) understand the interaction cross sections and interaction results, 3) visualise X-ray generation and detection features, 4) clarify the method of image reconstruction, and the features affecting the image quality in computerized tomography system. This is accomplished by changing the controllable variables of the radiation and the systems with the provided interfaces. In this thesis, JAVA/FLASH based simulation interfaces are designed to easily assess the subject. The benefits of these software are their ability to execute the programs prepared on the World Wide Web media. The interfaces are accessible from anywhere, at any time.

Investigating Glow Discharge Detectors as a Millimeter-Wave/Terahertz Radiation Detection Tool
Alasgarzade, N.; Nebioglu, M. A.; Takan, T.; Uzun Kaymak, İlker Ümit; Şahin, Asaf Behzat ; Altan, Hakan (2015-11-05)
Compared to other forms of electromagnetic radiation, Terahertz (THz) radiation is considered safe for imaging and detection purposes due to their non-invasive and non-destructive nature. Novel techniques and methods are constantly being evaluated for efficient detection and measurements of THz waves, yet their commercial success is limited due to cost and overall complexity of these systems. Commercially available Glow Discharge Detectors (GDDs) are proven to detect microwave and higher frequency radiation...
X-ray analysis of high mass x-ray binary pulsars
Şahiner, Şeyda; Baykal, Altan; İnam, Sıtkı Çağdaş; Department of Physics (2015)
In this thesis, X-ray properties of three high mass X-ray binary (HMXB) pulsars are analysed, using the data of X-ray satellites such as RXTE, INTEGRAL and Swift. Selected sources belong to different subgroups of the HMXB family. The first system, 4U 1907+09 is a classical wind-fed supergiant system with persistent X-ray emission; although it shows irregular flares and dips. SWIFT J1729.9-3437 and SWIFT J0513.4-6547 are newly discovered transient systems. Although the counterpart of SWIFT J1729.9-3437 could...

X-ray timing properties of four anomalous x-ray pulsars: 4u 0142+61, 1e 2259+586, 1rxs j170849.0_400910, and 1e 1841_045
Çerri, Danjela; Baykal, Altan; İnam, Sıtkı Çağdaş; Department of Physics (2015)
In this thesis, the detailed X-ray timing characteristics of four Anomalous X-Ray Pulsars (AXPs); 4U 0142+61, 1E 2259+586, 1RXS J170849.0 -400910, and 1E 1841- 045 are presented for glitch free time intervals using data taken by Rossi X-Ray Timing Explorer (RXTE). The pulse arrival times of these AXPs are evaluated by phase coherent timing method. After the removal of the spin-down trend from pulse arrivals, remaining residuals are used for estimation of their noise strengths. Possible correlation of the no...
Monitoring radiation induced alterations in biological systems, from molecules to tissues, through infrared spectroscopy
Demir, Pinar; Severcan, Feride (2016-01-01)
Humans can be exposed to non-ionizing and ionizing radiation for diagnostic, therapeutic, accidental, and occupational reasons. Consequently, the effect of radiation on biological systems has attracted the attention of researchers for a rather long time. This review is about the mid-infrared Fourier Transform Infrared (FTIR) spectroscopic characterization of non-ionizing and ionizing radiation-induced changes in DNA, lipids, and proteins, as isolated or synthetic macromolecules, and in biological membranes,...
