Abstract
A blood-mimicking fluid (BMF) suitable for use in Doppler flow test objects is described and characterised, The BMF consists of 5 mu m diameter nylon scattering particles suspended in a fluid base of water, glycerol, dextran and surfactant, The acoustical properties of various BMF preparations were measured under uniform flow to study the effects of particle size, particle concentration, surfactant concentration, flow rate and stability, The physical properties, (density, viscosity and particle size), and acoustical properties (velocity, backscatter and attenuation) of the BR-IF are within draft International Electrotechnical Commission requirements.
