Advanced methods for cardiac cells contour detection
Spíchalová, Barbora ; Čmiel, Vratislav (referee) ; Odstrčilík, Jan (advisor)
This thesis focuses on advanced methods of detecting contours of the cardiac cells and measuring their contraction. The theoretical section describes the types of confocal microscopes, which are used for capturing biological samples. The following chapter is devoted to the methods of cardiac cells segmentation, where we are introduced to the generally applied approaches. The most widely spread methods of segmentation are active contours and mathematical morphology, which are the crucial topics of this thesis. Thanks to the those methods we are able in the visual data to accurately detect required elements and measure their surface chnage in time. Acquired theoretical knowledge leads us to the practical realization of the methods in MATLAB.

Measurement of Isolated Cardiac Muscle Cell Lenght in real time
Klabal, Petr ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
Diploma thesis deals with the basic description of cardiac muscle cells, the mechanism of its contraction and events associated with contractions. There are different types of methods which can be used for measuring of contractions and for evaluation of cell length. This work describe these methods and evaluate their pros and cons. Based on available information and technical possibilities is one of the methods chosen and used for the design of block diagram system for measuring of contraction of isolated heart cells in real time. The practical part of this diploma thesis deals with the designing of a system which allows processing the image of isolated cardiac muscle cells that facilitate the detection of the cells edge. For this purpose it was created a device that allows the user to select a single row from television signal containing the image information from a location where is the currently selected row. Thus obtained image information can be used for cells edge detection and measuring of its length and contractions.

Modeling of action potential of heart cells
Zemánek, Ladislav ; Čmiel, Vratislav (referee) ; Rychtárik, Milan (advisor)
This bachelor’s thesis deals with studies and researches models of action potentials of cardiac cells. It offers a description of the various models including description of their current components. The own solution of this project includes reconstruction of models of cardiac cell in numerical computing environment Matlab and compared with literature.
