Magnetic Resonance Imaging: Basic MRI Physics

Target group

PhD students of the Doctoral School of Life Sciences and Medicine, (Bioscience) Engineering and Social and Behavioural Sciences who are current and/or future users of the MRI scanner at the GIfMI facility.

No previous knowledge of MR physics is assumed.


Magnetic resonance imaging (MRI) is a medical imaging technique used to produce high quality images of the body. Knowledge of the underpinning fundamentals of MRI is essential for every user – irrespective of previous experience. This course will prepare current and future PhD students for the use of the MRI scanner available at GifMI (Ghent Institute for Functional and Metabolic Imaging), a UGent research collaboration.


This course will provide the MRI user with a sound understanding of the practical process, hardware components, basic physical principles of MR imaging (localization of signal and generation of contrast) and digital signal sampling to generate an image from RF signals. It will provide basic physical principles that underpin MRI and of the many different data acquisition strategies in MRI.
