Purpose and Content

The aim of the course To introduce fundamental medical imaging methods and systems and to teach the basic physical and ethical principles of medical imaging. The course aims to provide an understanding of the structure, operating principles, and image formation concepts of analog and digital radiography equipment, and to impart the essential knowledge required to obtain error-free radiological images of optimum quality using the lowest possible dose, in accordance with the ALARA principle.
Course Content The Role and Importance of Medical Imaging in Modern Medicine; Duties of Medical Imaging Technicians and Basic Principles; Overview of Medical Imaging Modalities; Electromagnetic Wave Spectrum and X-rays; Mechanisms of X-ray Production and Interaction with Matter; Physical Principles of Radiographic Image Formation; Components of the X-ray Unit: Structural Characteristics and Functions of X-ray Tube Components (anode, cathode, vacuum tube, protective metal housing), High-Voltage Generator, Control Panel and Key Parameters Controlled Therefrom (kVp, mA, Seconds, mAs, Focal Spot Selection); Factors Determining X-ray Quality and Quantity (kVp, mAs, Filtration, Distance); X-ray Tube Rating Charts and Prevention of Tube Damage; Radiographic Image Quality and Selection of Operating Parameters; Digital Radiography Systems: Computed Radiography, CCD and Flat-Panel Detector Systems; Factors describing and influencing image quality in digital radiography; comparison of analog and digital radiography systems; structure and characteristics of mammography equipment; introduction to computed tomography; AI-based medical imaging devices.
