Measurement system for experimental determination of acoustic properties of gels at INRIM

Due to the large diffusion of ultrasonic technique in medicine, use of tissue mimicking materials to understand physical interaction of ultrasound has grown in importance. From this view measuring acoustic properties of such materials is crucial. This work shows the settlement at INRIM laboratory of a simple system for acoustic properties measurements with particular interest in attenuation of ultrasound. The system is based on substitution method and Fourier analysis and allow the evaluation of speed of sound, impedance and attenuation in the frequency range between 3 MHz and 12 MHz.
