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). Overview of other biomedical signals. Time and frequency domain analysis of the biomedical signals. Pattern recognition applied to the biomedical signals. Diagnostic medical imaging systems. Physiological systems modelling.

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

Forms of Teaching

Lectures

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

Seminars and workshops

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

Independent assignments

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

Laboratory

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

Grading Method

Continuous Assessment Exam
Type Threshold Percent of Grade Threshold Percent of Grade
Laboratory Exercises 50 % 10 % 50 % 10 %
Seminar/Project 0 % 10 % 0 % 10 %
Mid Term Exam: Written 50 % 20 % 0 %
Final Exam: Written 50 % 20 %
Final Exam: Oral 40 %

Comment:

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.
