概要	The accurate testing of the instrument by phantoms requires a tissue-mimicking material that has the acoustic velocity and density defined in IEC (International Electrotechnical Commission) standard, and furthermore it is granted that they are stable through time.To perform material with the desired acoustic velocity and density defined IEC standard, the tissue-mimicking materials have been newly developed. The form of tissue-mimicking materials reported in which polystyrene and PMMA (polymethyl metacrylate) particles are dispersed in Segmented Polyurethane Gel. They were stable over a period 40 days and the change in weight and acoustic velocity not exceeded 0.5 %
