Description
| - The pulse wave velocity (PWV) in arteries is determined mainly by the elasticity of the vessel wall. Therefore it can be used as an indicator of diseased blood vessels in the cardiovascular medicine. In our laboratory, the elastic properties of the arterial tissue are determined from the PWV. One of the methods for measuring the PWV is an optical method. A high speed camera records the displacements of the vessel wall loaded by a pulsatile flow and the propagation of the equal displacement values is evaluated. However, the shape and elastic properties of the biological specimen vary along the axis of the tube; therefore the PWV is not constant. To detect the local changes of the PWV, high space and time resolution is needed. Therefore, the correlation of two camera records (the Q-450 system) is one of the promising possibilities for measuring the PWV in vitro

- Rychlost pulzní vlny v tepnách je určena mimo jiné pružností cévní stěny. Proto může být tento parametr použit v kardiovaskulární medicíně ke stanovení zdravotního stavu cévních stěn. V naší laboratoři stanovujeme elastické vlastnosti tepenné stěny z rychlosti pulzní vlny měřené in vitro. Jednou z metod je metoda optická. Vysokorychlostní kamera zaznamenává posunutí cévní stěny zatěžované pulzním prouděním a časový posuv stejného posunutí je vyhodnocován. Vlastnosti pravých cévních stěn se ale mění podél osy a proto ani rychlost pulzní vlny není konstantní. Aby bylo možno tyto změny zjistit, musíme věřit s vysokým prostorovým a časovým rozlišením. Proto byly zkoumány možnosti korelátoru Q-450 pro tato měření. (cs)
