Abstract
This paper presents the metrological study of long-term stability of the ultrasonic properties of a tissue-mimicking material (TMM) manufactured in 2013. The thickness, speed of sound and attenuation coefficient of TMM were estimated by the pulse-echo technique. The Student’s paired t-test was applied and the averages of the speed of sound and the attenuation coefficient in the four years-old TMM did not differ statistically from the reference values presented in the standard.
