Teaching Methods

Theory lessons on physical principles underlying the imaging techniques, technical details on instrumentation, currently in use and that under development. Practical classes including laboratory measurements and computation experience; visits to medical imaging units and scientific laboratories where demonstartions take place, some with participation of the students. Elaboration on a topic related with the subject with emphasis on state-of-the-art techniques and new developments and its public presentation.

Learning Outcomes

Acquisition of theoretical and practical knowledge in the field of medical imaging instrumentation with emphasis on the undelaying physical principles of different types of medical imaging techniques and instrument functioning as well as on image acquisition.
Capability to relate the physical processes leading to the image formation with diagnostic information that can be obtained from different types of images.
Become familiar with the most commont imaging modalities.
