Teaching language

Suitable for English-speaking students

Objectives

Address the physical principles, the mathematical and computational methods, and the implementation of the most relevant techniques of medical imaging using Magnetic Resonance and Ultra-sounds, as well as the image characteristics and associated quality control. At the end of the course, the student should understand the working principles of medical imaging techniques and of the global physical aspects of their application: ultrasonography and nuclear magnetic resonance, and have competences on quantitative analysis of the implementation of those techniques.

Learning outcomes and competences

Knowing the basic principles of different imaging techniques and their clinical uses.
Knowing the equipment used and in order to quality control.
To know the main applications and limitations of imaging techniques.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Basic principles of the electromagnetic theory, statistical physics, quantum mechanics, solid state physics and calculus. Fourier Transform.
