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.
