“…The mixture comprises 88.1 % water weight, 11.9 % glycerol weight, and 0.5 % benzalkonium chloride weight. According to [2], the water-glycerol-benzalkonium chloride mixture adds to keep the long-term stability of ultrasonic properties of the phantom. In 2018, Souza et al [2] assessed the long-term stability of the ultrasonic properties of a four years old TMM.…”

“…The phantom's properties traceability is requisite to carry out reliable tests in evaluating the safety of ultrasonic physiotherapy equipment. There are several studies of the ultrasonic properties of agarose phantoms [2][3] [4]. The TMM's ultrasonic properties measurements, such as ultrasonic velocity and attenuation coefficient, are usually carried out in the experimental setup underwater.…”

The present paper studied the metrological impact on the ultrasound group velocity in not storing the agar phantoms in the water-glycerol-benzalkonium chloride maintenance mixture. The ultrasonic velocity and the phantom’s thickness were measured by the pulse-echo technique seven times within 44 days, whereas four replicates were carried out under repeatability conditions. The phantom’s thickness did not differ statistically along the days since the normalized error was less than 1.0. Based on the results obtained, one can conclude that the ultrasound group velocity decreased in a logarithmic function along the days.

Agarose-based phantoms are widely used to evaluate ultrasonic equipment used for diagnosis. Many studies report phantom’s ultrasonic characteristics as a function of frequency, mainly sound velocity and attenuation, but a metrological approach is not widely spread. The current paper reports attenuation coefficient (Att-c) and speed of sound (SoS) in an agarose-based phantom as a function of the diagnostically used frequency, ranging from 2.25 MHz to 10 MHz, at 21 °C. The pulse-echo method was applied to measure the ultrasonic properties. The measurements were performed under repeatability conditions (no = 4) and the expanded uncertainties of the measurements were estimated thereafter. It was observed that there was no statistical difference among the values of SoS (average of 1,540.3 m s-1) for all frequencies, in which the maximum E<sub>n</sub> = 0.98. The SoS result with the highest uncertainty was of 1,538.7 m s-1 ± 3.8 m s-1 (k = 2; coverage probability p = 0.95). Att-c increases as a power function of frequency (Att-c = f 109; α0 = 0.573; R2 = 0.9995. A survey of the literature was made and it was found that Att-c values obtained in this research are consistent with the previously reported. Based on the SoS, this study draws attention to the importance of performing a statistical test to assess the consistency of the results.
