Supervisor:
Department of Biomedical Technology
Synopsis:

The aim of the course is to introduce the students with basic knowledge (physical and technical background, basic measurement principles and application examples in diagnostics and therapy) of this innovative field of research being on the cusp to commercialization and clinical practice.

Requirements:

In the case of foreign lecturers, there will be a weeklong block of intensive contact education for the number of students at least five. If the number of students is less than five, the course will be self-study with consultations using VoIP (e.g. Skype) and a contact 1- or 2-day seminar. The contact seminar will take place at the FBMI or at the home institution of a foreign lecturer. The subjects are concluded by an oral examination. The student must elaborate a paper on a given topic together with the exam in case of the controlled self-study. Assessment will be based on active participation in the discussion exercises, reports of group work and presentation of the research protocol conducted during the workshop.
