Measurement and processing of biomedical signals

Advanced overview of selected signals of biological origin encountered in research or in medical clinical environment. Physiological origin and typical properties of these signals. Physical background and application of methods for acquisition and measurement of these signals. Electrodes and probes for acquisition of non-electrical quantities. Signal processing methods in time and frequency domain for extraction of clinically or experimentally relevant information about the biological system. Concrete examples of application.

The signals of these origins are to be discussed: electrophysiological signals (electrocardiography, electromyography of skeletal and smooth muscles, electroencephalography, nerve conduction); blood flow (ultrasound, laser Doppler); oxygenation (near infrared spectroscopy and methods for oximetry); measurement of biological cell properties (microscopy and spectroscopy).

To gain knowledge and understanding of the methods for acquisition and processing of different physiological signals from the practical point of view of extracting relevant information (for clinical or reserch use) about properties and function of a biological system. By working on a project students can apply this knowledge to solving a concrete problem on a selected topic.

Lectures in case of sufficient number of students, otherwise independent study with regular individual consultations.

Every student is presented with a concrete applicative project on a selected topic from biomedical signal measurement and processing and is expected to find a solution to the problem based on literature search and practical work.
