Goal
  • The purpose of the discipline is the acquisition by students of a complex of knowledge and practical skills in the analysis of various biomedical signals, images and data (using the example of various systems of the human body), as well as in the processing of images obtained using visualization and functional diagnostics methods (pre-filtration method, selection of characteristic points of the object, segmentation, method of registration of electrical potentials, etc.).
Objective
  • Study of principles, methods and algorithms for processing and analyzing biomedical signals, images, as well as methods for synthesizing appropriate software-algorithmic tools used in medical systems.
  • Consideration of modern trends in the development of information technologies and prospects for their use in medicine.
  • Acquisition of skills to work with scientific literature for the independent solution of research and applied tasks in this field of knowledge.
Learning outcome: knowledge and understanding
  • Describe signal quality issues and ways to eliminate artifacts.
  • Describe modern methods of digital processing of biosignals (filtering, time-frequency analysis, predictive modeling).
Learning outcome: applying knowledge and understanding
  • Use digital signal processing tools (Python, MATLAB).
  • Filter biosignals and eliminate artifacts (network interference, signal drift, physiological noise).
  • Analyze biosignals using Fourier and wavelet transforms.
Learning outcome: formation of judgments
  • Analyze the quality of biomedical signals and assess the reliability of the obtained data.
  • Select the best data processing methods depending on the type of sensor and the purpose of the study.
Learning outcome: communicative abilities
  • Describe and explain the principles of operation of biomedical sensors and their application in medicine, both to specialists and non-specialists
Learning outcome: learning skills or learning abilities
  • Master new methods of digital signal processing and machine learning.
  • Apply modern analytical tools for processing biosignals.
Teaching methods

interactive lecture (use of the following active forms of learning: guided (controlled) discussion or conversation; moderation; demonstration of slides or educational films);

search and research (independent research activities of students during the learning process).

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

  • 40% of the examination result;
  • 60% of current control result.

The final grade is calculated by the formula:

FG = 0,6 MT1+MT2 +0,4E
2

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:

Alphabetical grade Numerical value Points (%) Traditional grade
