Description
  • Measurements of the pulse wave velocity (PWV) in human arteries are important for two different reasons: an early diagnostics of atherosclerosis and identification of material properties of the vessel wall for numerical simulations. The PWV in blood vessels is not constant and classical methods of pressure wave shift between two points are not sufficient. We consider three methods: optical measurements of vessel wall displacement in several points by high speed camera, continual optical measurements of vessel wall displacement by correlator Q-450 and measurements of flow rate and displacements by ultrasonic device. The first method can determine the PWV only between several points. The second method can show 3D reconstruction of displacements with very good resolution. The ultrasound measurements need combination of Doppler ultrasound velocimetry and B-scan imagining. However, the common devices used in medicine do not have any data output. It causes bad resolution.

  • Měření rychlosti pulsní vlny v lidských tepnách je důležité ze dvou důvodů: včasné diagnostiky atherosklerózy a identifikace materiálových vlastností cévní stěny pro numerické modely. Rychlost pulsní vlny v cévách není konstantní a klasická metoda měření časového posunu tlakové vlny mezi dvěma body je nedostatečná. Uvažujeme o třech metodách měření: optickém měření posuvů cévní stěny v několika bodech kamerou s vysokou snímkovací frekvencí, kontinuální optické měření posuvů cévní stěny korelátorem Q-450 a měření průtoku a posunutí ultrazvukem. První metoda je schopna určit pouze průměrné rychlosti pulsní vlny mezi měřícími body. Oproti tomu, korelátor se dvěma vysokorychlostními kamerami rekonstruuje 3D posuvy s velmi dobrým rozlišením. Ultrazvuková metoda využívá kombinace Dopplerovského ultrazvuku a tzv. B-scanu. Přístroje používané v medicíně však většinou nemají datové výstup a to zhoršuje kvalitu rozlišení. (cs)
