Non-Ionization Radiation: Physics, Equipment and Applications

Semester 1

The aim of the module is to present to the students the theoretical and practical basis of non-ionisation radiation: principles, instrumentations and their medical applications for diagnostic and therapy. In Part A, the emphasis is not on the more advanced MRI techniques, but on the development of a solid understanding and application of the basics of image formation and spatial accuracy, image contrast clinical applications, and safety. In Part B, the emphasis is on the application of the principles of acoustic physics, interaction of ultrasound with tissue, ultrasound transducers and arrays, and ultrasound imaging and Doppler instrumentation. In Part C, we examine lasers, how they work, their characteristics and medical use.
