This comprehensive course, Fundamentals of X-ray Physics and Imaging Technology, is designed to provide a solid foundation in the principles, mechanisms, and technologies that underpin modern radiographic imaging. Whether you are a radiology student, technician, or healthcare professional, this course offers a clear and structured understanding of the physics behind X-ray production and image formation.The course begins with an introduction to atomic structure, followed by an in-depth look at X-ray generation through cathode-anode interactions. It covers the components of the X-ray tube, including the role of the focal spot, anode heel effect, and the importance of filtration and collimation in image clarity.As the course progresses, you'll explore the underlying physical interactions such as Bremsstrahlung and characteristic radiation, the photoelectric effect, and Compton and elastic scattering. Special emphasis is placed on beam quality, spectrum, and linear energy transfer-critical concepts for both diagnostic performance and radiation safety.Advanced imaging technologies are also covered, including digital and computed radiography, thin film transistor arrays, and screen-film systems. You'll learn about detector types, characteristic curves, and image processing techniques.Finally, the course delves into factors affecting image quality-such as geometric unsharpness, magnification, and scatter radiation-and introduces methods for optimization, including anti-scatter grids.By the end, learners will gain both theoretical insight and practical understanding essential for mastering X-ray imaging.
