Abstract

Present thesis focuses on Cone Beam Computed Tomography (CBCT) technology and its significance in the field of medical imaging. The thesis provides an overview of the history of CBCT, its operating principles, the differences between cone beam and computed tomography, and the advantages of CBCT over CT. Additionally, it delves into the principles of CBCT scanners, the different types of CBCT machines and their functionalities, as well as the image reconstruction process. The physical aspects of CBCT and image quality are also addressed, along with the analysis of three-dimensional imaging and the clinical applications of CBCT, particularly in the field of cephalometry. Furthermore, the thesis discusses radiation doses and protection regulations, as well as methods for reducing personnel exposure. The utilization of phantom models for simulation purposes is employed to capture and study detailed results. In conclusion, the findings of the thesis are summarized, and future prospects for the advancement of CBCT technology in medical imaging are proposed, emphasizing continuous improvement and adaptability to meet the evolving needs of the medical community.
