Abstract

The knowledge of ultrasound contrast agent (UCA) behaviour is continuously improving, mainly thanks to "invitro" measurements performed by means of specific phantoms, mimicking the acoustic properties of severalhuman body districts. For such purposes, it is necessary to develop experimental setups able to minimisechemical and physical effects due to environmental conditions. In this paper we discuss the design of a newtissue-mimicking phantom, specifically evaluating the sound-absorption properties of three synthetic materials(Polyurethane, Airex©, ethylene vinyl acetate (EVA©)) laid on the bottom of the phantom. Our goal is toestablish the best material to use in order to minimise the artefacts within the tissue-mimicking matrix.Polyurethane showed the best sound-absorbent behaviour for every tested ultrasound frequency, so itsemployment in covering the bottom of tissue-mimicking phantoms is suggested in order to allow experimentalinvestigations of acoustic properties of different UCAs without additional aspects due to environmentalboundary conditions.
