Spectral analysis of the EEG signal
Blatný, Michal ; Kozumplík, Jiří (referee) ; Hrozek, Jan (advisor)
Master’s thesis deal about electroencefalography, measurement EEG signals and analysis measuermed signals. Project contains two basis practical parts. Firts part contain two PC’s programs that’s are used to fundamental analysis to frequence-domain and visual display of brain mapping created with Matlab. Second chapter of practical parts includes two PC’s programs created with LabView. First of them is the EEG biofeedback making use for advanced analyses and second program is used to detection segment of stacionarity.

Psychogalvanometric measurement and biofeedback
Paulasová, Lenka ; Čmiel, Vratislav (referee) ; Hrozek, Jan (advisor)
This work deals with bio-feedback and the possibility of measuring changes in skin resistance for biofeedback. The Theoretic part is focused on the principle of biofeedback and its use. Next deals with the resistance of the skin, the changes depending on the emotions and the measurement this change . The practical part is devoted to the creation program for the use of skin resistance to change biofeedback in LabVIEW.

The radio therapy process planning
Slavíček, Tomáš ; Kolářová, Jana (referee) ; Hrozek, Jan (advisor)
This thesis aims to bring reader to the problems of radiotherapy, to give him an overview of basic principles and methods used to treat patients with cancer by ionizing radiation. The first part is devoted to the physical description of radiation and means of quantification. Interactions of radiation with matter are discussed next following with characterization of radiation effects on living cells and tissues. In the next part there is a description of the devices used in the treatment by ionizing radiation and an explanation of the various acts of patient's preparation from the target localization to irradiation. The final chapter describes created program with a graphical environment, which includes the key elements of commercial planning systems for the creation of the irradiation plan. This program uses real CT images and provides the user a basic idea of creating radiotherapeutic plan. The user has several functions for creating and optimizing the plan. The output of the program is a graphical representation of the spatial distribution of dose in the patient's body.

Biofeedback and its practical use
Dvořák, Jiří ; Hrozek, Jan (referee) ; Čmiel, Vratislav (advisor)
The aim of this work is describe common methods of biological feedback therapy that is used to treat some psychosomatic diseases. Subsequently, the description is focused on minimal brain dysfunction treatment by the help of EEG biofeedback. Properties and technical requirements for this therapy are concretized. The last part of this thesis is dedicated to the design and realization of practical software tool for EEG biofeedback therapy which is made in LabView 7.1. The M535 acquisition unit and NI USB-6221 measuring device are used for hardware solution.

Audiovisual stimulator
Bartoš, Michal ; Čech, Petr (referee) ; Hrozek, Jan (advisor)
The main objective of this study is to learn about the audiovisual stimulator and to create hardware resolution of stimulation LED glasses and in environment of the program LabView application, which operate this stimulation LED glasses and in the same time create sound of stimulation. Use environment of the program LabView. Application, which is create in environment of the program LabView, enable operate stimulation LED glasses and arrange sound from three source with two different method, which use modern AVS. Application contains a lot of security, informative and agreement components.

EMG biofeedback
Toman, Jakub ; Hrozek, Jan (referee) ; Janoušek, Oto (advisor)
The bachelor´s thesis describes the basic methods of bringing out the electromyographic data by invazive and noninvazive procedure. Further it is focused on the principle of the biological feedback and on the myofeedback and its essential characteristics. The created application can displays the progression of the maesured EMG, signalizes the overrun of the set up threshold and contains two simply games for myofeeedback.

Penile plethysmography
Koudelková, Zuzana ; Harabiš, Vratislav (referee) ; Hrozek, Jan (advisor)
This bachelor´s thesis focuses on methods that examine volumetric changes of genital organs (especially for volume changes in male sexual limb). These changes are used in the sex diagnosis. The most common type of examination is to determine sexual preference of the patient. The aim of this work is to describe how have been the changes investigated previously and how they are investigating in the routine practice now. Find out which are their limits. Try to build a new type of sensor which could help to better evaluate the volume changes. And try to create a program in LabVIEW environment in which the measured data is displayed and stored.

Electroencephalography and audio-visual stimulation
Hrozek, Jan ; Hlaváček, Antonín (referee) ; Kolářová, Jana (advisor)
This thesis deals with questions of scanning electric activity of brain,¬ so-called electroencephalograph (undermentioned EEG), methods of audiovisual stimulation (undermentioned AVS) and a data-measurement processing. Theoretical part of the thesis is engaged in a theory of EEG signal creation, history and even in current methods of purchasing and processing of the EEG signal, theory of AVS and a theory of biofeedback. For measuring EEG signal with or without an application of AVS methods has been used EEG diagnostic device by Alien company. Its attributes are described in the thesis as well. For elaboration and analysis has been created a programme aplication EEG_xhroze00.fig which realizes frequency spectrum analysis using Fast Fourier Transform algorithm (FFT) and another programme aplication brain_mapping.fig for mapping activity of brain using designed algorithm.

Electrical installation of surgery room
Pospíšil, David ; Rozman, Jiří (referee) ; Hrozek, Jan (advisor)
The main objective of this bachelor´s thesis is to get know about essentials of electrical installations with aim for medical applications, standards and requirements. Characterization of component’s parameters used in the course of surgery rooms realization icluded as the same as description of applied medical devices and its engineering solution. Own realisation of project comes at the end. Reader of this bachelor´s thesis will take an image about planning electrical installations, its usage in health service and will have a concept of medical parts in this branch, modern equipment, its parameters and acquirements. He will know about principles of mentioned machinery.

Audiometry
Stanický, Ondřej ; Chmelař, Milan (referee) ; Hrozek, Jan (advisor)
The first part of the thesis focuses on theory and deals with the basic physical terms as far as acoustics is concerned. It also deals with a description of auditory system, as well as graphical results of audiometrical methods. The second part to the thesis deals with a scheme of audiometer for hearing tests. It also deals with the description of the programme as well as the transfer of the decibel scale to electric voltage and its correction. The last chapter contains the data collected during the hearing tests.
