Ultrasound phantoms in medical diagnostics
Koňaříková, Anna ; Pekař, Miloslav (referee) ; Hurčíková, Andrea (advisor)
This bachelor’s thesis studied the relative ultrasonic velocity of gel matrices made of gelatine, agar or agarose depending on concentration and time. These properties have been studied both in the air and water environments, using high resolution ultrasonic spectroscopy. In additon, the basic properties of gel matrices, such as desiccation or moulding, were observed. Relative ultrasonic speed has been found to grow linearly with sample concentration and its changes over time are minimal. Basic gel matrices without added preservatives are able to withstand the usable state only for a week.
