Learning outcomes |
This course aims to disseminate the applications of lasers in medicine, as well as the basic concepts of physical optics that allow for their understanding. By the end of this course, the student should be able to identify and characterize various types of laser systems (and associated optical systems) for therapeutic applications. The student should be able to understand the biophysical mechanisms of laser light interaction with biological tissues. The student will become familiar with some experimental techniques for studying laser-tissue interactions. It is also intended that the student will understand the current landscape of laser applications in medicine within a national context.

Teaching Methodologies and Assessment Criteria |
The teaching/learning activities of this discipline comprise theoretical-practical classes and laboratory practices. Students also learn the content related to the skills to be acquired through programmed online activities in the form of quizzes, using distance learning platforms such as Moodle. There will be a set of laboratory activities where the student will become familiar with some experimental techniques for studying laser-tissue interactions. At the end, the student should be able to recognize the physical principles underlying the functioning of lasers and describe some of their medical applications. Project-based learning is promoted through the presentation of a therapeutic application challenge of light in a wearable system that students will have to develop in the form of a laboratory prototype. This activity may be developed in collaboration with other course units.
