Teaching methods

Lectures with presentation of slides and audiovisuals

Assessment methods

Final exam to verify the knowledge and skills expected in the field of physics applied to Magnetic Resonance, through an oral test that includes at least 3 open questions on the main topics covered during the lessons.

Evaluation is based on the following parameters:

- knowledge of the contents

- critical and expository capacity

- technical-scientific language correctness.
