Course objectives

Biofysics forms theoretical base for almost all modern therapeutical and diagnostical medical devices. The main learning objectives of these practical sessions are: a development of the measurement and instrument use skills of students, the development of a scientific, effective, safe and efficient attitude to the use of biomedical devices, a healthcare practice oriented understanding of the biophysics principles directly related to the management of patients (which are the basis of many medical imaging and physiological monitoring

Learning outcomes

At the end of the course students should be able: understand and explain biophysical principles and laws; operate basic biophysical devices; evaluate obtained data by the basic biophysical methods in light of a scientific, effective, safe and efficient attitude to their use; understand principles of the more complex therapeutical and diagnostical medical devices; discriminate possible usage of the biopfysical techniques and medical devices in practice.
