Medical Microwave Sensing

Course guarantor:

Marko Helbig

Lecturer:

Marko Helbig

Tutor:

Ondřej Fišer, Marko Helbig, David Vrba, Jan Vrba

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.

Two laboratory exercises are required for admission to the exam (attested by a protocol signed by the student, the tutor and the supervisor of the course).

The protocols will be archived in the Department for Doctoral Studies.
