Region tracking in ultrasound sequences
Byrtus, David ; Harabiš, Vratislav (referee) ; Slávik, Vladimír (advisor)
Thesis deals with ultrasonographic contrast examinations, that are performed to assess tissue perfusion and non-invasive ultrasound method speckle tracking, overcoming the weaknesses of Doppler techniques used to scanning the movement of the tissue.
Localization of a Moving Target using a MIMO Radar System
Šulc, Martin ; Vychodil, Petr (referee) ; Škorpil, Vladislav (advisor)
The aim of this thesis is to estimate parameters of the moving target using different radar configurations. First the Doppler effect and the time delay of the received signal is examined. The investigation of these phenomenons is made for radial and non-radial movement of simple monostatic radar configuration and after that for the bistatic and multistatic MIMO configuration. The ambiguity function is presented for all these configurations. The ambiguity function is then used to estimate target parameters from the received signal. The received signal model and ambiguity function for the monostatic radar configuration is developed using Matlab software. Finally the practical use of these implementations is presented and compared.

Speckle noise suppression methods in ultrasound images
Teplý, Lukáš ; Harabiš, Vratislav (referee) ; Mézl, Martin (advisor)
Ultrasound investigation is one of meaningful imaging at present. Advantages of ultrasound are, that it hasn´t side effects as a rtg radiation and it is noninvasive. Ultrasound diagnostic is exploited in all branch of medicine (urology, cardiology, orthopeadist, gynecology etc.) to display organs, tissues and cavities of the human body. We use display in 2D, 3D and most modern display in 4D. We can encounter with many kinds of artifact. Artifacts are described more closely at 3rd chapter. Speckle noise deteriorates informative yiled of ultrasound picture. We try to remove speckle noise by simpler methods or more complex methods of filtration. These methods are described at 5th chapter. Programme for speckle filtering from pictures is part of this master´s thesis.
Traffic Doppler Radar
Kulig, Radomír ; Józsa, Ladislav (referee) ; Šebesta, Jiří (advisor)
This work deals with problematics of speed measurement of an object with a Doppler radar. This radar communicates with other environment through RS232 interface. The complete solution of this Doppler radar is provided in the thesis. There are electrical schemes of all parts and program to control microcontroller in this work. Speed measurements for the radar are summarized in the end of the work.
