Vývoj fantomu krku pro dynamické ultrazvukové měření hemodynamiky

Abstract

This bachelor's thesis deals with the development of a neck phantom for dynamic ultrasound measurements of hemodynamics. The main goal is to create a physical model that faithfully simulates both the anatomical and physiological properties of the human neck, focusing on the area of large vessels - especially the carotid artery (arteria carotis) and jugular vein (vena jugularis). The phantom is constructed to imitate the acoustic and mechanical properties of soft tissues and bone structures, which is necessary for the correct propagation of ultrasound waves. For this purpose, materials and additives in them were tested to find different echogenicity on ultrasound imaging. At the same time, the phantom allows the display of the Doppler effect and thus the measurement of flow velocity, as if it were a real blood circulation. The use of this phantom is for educational purposes, where it will serve as a teaching aid for students of medical and technical fields in learning the principles of ultrasound imaging and hemodynamic measurements. The result of this bachelor's thesis is a functional phantom prototype that provides repeatable use for experimental ultrasound measurements and is also completed by the creation of a laboratory task for educational purposes.
