The most common scattering particle materials for preparation of Blood Mimicking Fluid (BMF) are the nylon (Orgasol) and the polystyrene. These scatters particle materials density must be equal with mixture fluid density during preparing BMF. In this research study, low cost and less consuming time of a new proper ternary mixture fluid for the preparation of BMF was used to be suitable for the nylon (Orgasol) or the polystyrene density as a scattering particle material, for keep neutrally buoyant. This BMF proper for utilizing in Doppler flow phantom or test objects. The polystyrene and nylon particles were used for suspension in a mixture fluid base of three items, distilled water, propylene glycol and glycerol. The diameter of polystyrene particles is 30 µm, where its density 1.050 g/ml. While the diameter of nylon particles is between 5-15 µm, where its density depends on the type of nylon. Both the acoustical (speed of sound and attenuation) and physical (density and viscosity) properties of the mixture fluid or BMF were measured and agreed with draft International Electrotechnical Commission (IEC) requirements and values.
