Biomedical Signals and Systems

Course Description

The discipline of biomedical engineering, a historical perspectives and contemporary trends. The human body: an overview. Basic electrophysiology. Cell and cellular mechanisms. Bioelectricity. Physiologic systems. Nervous system. Muscular system. Circulatory system. Respiratory system. Sensing systems. Homeostasis. Body as a control system. Bioelectric potentials and their main features (ECG, EEG, EMG, ENG and ERG). Registration techniques and problems. Electrodes. Overview of other biomedical signals. Therapeutic electromedical equipment. The most important techniques and devices. Diagnostic medical imaging. Equipment and techniques. Fundamental physical and medical limitations. Methods for quality evaluation processing. Estimation of diagnostic value processing. Patient safety and safety assurance in modern medical facilities.

General Competencies

The purpose of this course is to serve as an introduction to and an overview of the field of biomedical engineering. Considering this purpose, a link between biomedicine and electrical engineering will be given. Students should be able to understand and define the discipline of biomedical engineering, basic physiological and electrophysiological mechanisms, basic bioelectric signals, electrodes and registration techniques. They will also acquire an introductory knowledge about the most important diagnostic and therapeutic electromedical equipment and safety assurance in medical facilities.

Learning Outcomes

  1. describe physiological systems in the human body
  2. distinguish main features of biomedical signals
  3. describe biomedical signal registration techniques
  4. compare biomedical signals registration and analysis methods for the particular problem solving
  5. explain functioning of diagnostic medical imaging systems
  6. appraise applicability of the particular medical imaging method

Forms of Teaching

Lectures

Lectures are focused on theoretical and practical aspects of key course topics (two hours per week).

Exams

Continuous evaluation encompasses two written exams (midterm and final exam). Students who do not satisfy at continuous evaluation must undertake both the written and oral exam. Students are questioned at the laboratory exercises and they also collect the points for a practical project.

Laboratory Work

Students are obliged to take laboratory exercises (15 hours). During the laboratory exercises, students learn about biomedical signal measurement and analysis on practical examples.

Consultations

Consultations for students are held once per week.

Seminars

Students (in groups of up to three students) explore a theme or subject of interest related to the course.

Internship visits

During the semestar, professional visits to laboratories for recording and analysis of biomedical signals will be arranged.
