Synopsis:

Students will study fundamental principles applied within the modern medical devices and systems, esp. from thr point of view of functional blocks and electronic circuits of diagnostic and therapeutic medical equipments including: electrocardiographs, electroencephalographs, bedside and central monitors, equipments for anesteziology, intenzive and critical healthcare, equipments for clinical laboratory, electrostimulators, cardiostimulators and defibrilators, equipments for audiology and opthalmology, blood pressure and flow measurement (including dilutuion), pulse oxymetry. The syllabus within the therapeutic equipments concentrates mainly on hearing aids, cochlear neuroprosthesis, therapeutic applications of ultrasound, design and utilisation of ultrasonic systems, rhinometry and radiation equipment.
