F7ADIZAB - Processing and Analysis of Biosignals

The aim of the lectures is to provide information of principles of genesis of the basic biosignals including recordings, pre-processing and visualization of the results.

1. Biopotentials, stimulation and evoked potentials. Electrical activity of the brain. Genesis of the most important signals.

2. Biosignals of the skeleton, EMG. Origin of ECG. Polysomnography.

3. Acquisition of electrical biosignals. EEG, ECG, EMG, ERG, EGG.

4. Nonelectrical parameters recordings. Optical sensors screening, termovision, RTG, signal processing in nuclear medicine, ultrasound systems, sonar.

5.Analog filtering. A/D a D/A conversion. Sampling. Aliasing. Fourier transform.

6.Digital filtering – FIR (Finite Impulse Response) filters, IIR (Infinite Impulse Response) filters. Filters design.

7.Spectrum analysis. Power Signal Density. Parametric and nonparametric methods. Periodogram spectrum estimation. Cross spectrum, coherence and phase, cordance. Signal spectrum analysis and synthesis by Fast Fourier Transform.

8. Digital image processing, Computer vision. Brightness histogram and transformation. Morphologic transform, geometric transform.

9. Processing in space area – convolution, noise filtering and edge detection. Segmentation of objects in picture.

10. Principles of MR screening, gradients. Space coding, resolution, pulse sequence.
