Purpose Acoustic characterization of tissue mimicking materials in terms of attenuation, absorption, scattering, and propagation rate is critical for their use in experiments, reducing the need for living tissues or cadavers. Although there is a large literature on the acoustic characterization of such materials in terms of attenuation or propagation velocity, there is no evidence on the scattering coefficient. Herein stimulated the use of four agar-based phantoms with different types of scattering agar-structures on one of their surfaces in order to obtain experimental data on scattering's severity. Methods The agar-based phantoms were produced with 6% w/v silica and 4% w/v silica, as well as embedded scatterers of sizes 0 to 13 mm. Conclusions The experimental findings show that the procedure for determining the scattering coefficient of tissue mimicking materials improves ultrasound diagnostic and therapeutic uses of ultrasound.
