Analysis of heart rate variability in animal models
Řehořková, Iveta ; Ronzhina, Marina (referee) ; Kolářová, Jana (advisor)
This paper deals with the analysis of heart rate variability (HRV) in animal models. The first part discusses, the basic information concerning the ECG, both in humans and in individual laboratory animals. This is followed by an introduction to the topic of heart rate variability, a description of methods for its determination and the effects of pathologies on HRV values. Prior to the practical section, the methods of ECG acquisition in animal models are discussed, and the function of the perfusion model used in capturing data for this work is also described in detail. The last part deals with the analysis of HRV provided data, performed in Matlab environment and an evaluation of the chosen methods.

Simulation of dose distribution irradiation
Večeřa, Petr ; Hlaváč, Martin (referee) ; Kolářová, Jana (advisor)
This project deals with the issue of simulation of dose irradiation. This principle is used in a radiotherapeutic device known as a Leksell Gamma Knife for the treatment of intracranial tumours. With regard to the theoretical observations obtained by studying this device, the project suggests the use of analytical geometry for the creation of a mathematical model for calculation of the intensity in the rayed area. A demonstration program Leksell_xvecer08 has been created for this model in a MatLab software background, which enables the user to change various input arguments and simulate a picture of the dosage spread in the target scanned areas.

Drawning test digitalization
Sűsserová, Martina ; Kolářová, Jana (referee) ; Janoušek, Oto (advisor)
This thesis deals with the digitalization of Rey-Osterrieth tracing drawing test. The first part describes the issue of drawing tests in psychology with focus on Rey-Osterrieth complex figure. Also there is designed way of line separation. The second part is devoted to the application designed to visualize the sequence of drawing and to evaluate its complexity. It also evaluates dynamic parametres of the drawing. In the last part of the thesis is the statistical evaluation of calculated parameters and designed normative.

Electrogram processing and analysis
Hanák, Pavel ; Kolářová, Jana (referee) ; Janoušek, Oto (advisor)
The aim of the study was focused on problem of electrograms recording from alive tissue. Study of electrograms recording was extended with noise analysis and its elimination. Elimination of noise and disturption was made in program Matlab; lowpass filtration and wavelet transformation was used. Application for electrograms analysis was developed in latter part of this work.

Radiotherapy planning
Běťák, Ondřej ; Janoušek, Oto (referee) ; Kolářová, Jana (advisor)
The thesis is dealing with usage of ionizing radiation in radiotherapeutical treatment and designs demonstrative function for modelling the final radiation field in Matlab. The fundamentals is based on Leksell gamma knife . Leksell gamma knife uses 201 sources a it’s purpose is to treat tumours in brain tissue. The sources are placed static. In demonstrative function are 8 sources instead of 201 and there is 2D exposuring. The sources are equalized in defined coordinates in matrix 100x100. In demonstrative function is possible to set the number of activated sources, it’s beam width in isocentre and indirectly the angle of rotation of sources.

Electrocardiogram processing
Miščík, Peter ; Kolářová, Jana (referee) ; Ronzhina, Marina (advisor)
The topic of this bachelor's thesis is electrocardiogram (ECG) processing using LabView. The main part of a program for processing the ECG, particular suppressing various noises and detection R-peaks, is created in LabView environment. Used components and realization of individual parts of program are described in manual, achieved results are shown in pictures.

Measurement of biosignals with usage of Biopac system
Rageh, Akram ; Kolářová, Jana (referee) ; Janoušek, Oto (advisor)
This work describes a brief overview of measurement of Electroencephalography (EEG), Electromyography (EMG), Electrooculography (EOG), Electrocardiography (ECG) and theirs usage. Subsequently is described how these biosignals can be measured with Biopac system. The measurement of electrocardiography is described in detail, including ECG curve description, Biopac measurement system and R-R intervals analysis based on measurement of group of volunteers.

Non-contact measurement and analysis of vital signs
Kolářová, Jana ; Mézl, Martin (referee) ; Odstrčilík, Jan (advisor)
The theme of this barchelor´s thesis is to process the video record of a human face to detect vital parameters - heart rate, respiratory rate were chosen. The purpose is a contactless and painless method to determine these parameters, both for the simpler gain of these data in newborns and more natural values without the influence of any subconscious fear of the devices. Or as a method of verifying work ergonomics, workplace stress, depending on the regularity of the rhythms of these parameters. The solution has been focused on testing its function and accuracy under various acquisition conditions, and has been able to reliably verify its reliability under defined scanning conditions.
