Speed of sound in rubber based materials for ultrasound phantoms. We have discovered such a material in the form of water based pharmaceutical gels containing uniform distributions of graphite powder and known concentrations of alcohol. Paraffin gel waxes have been investigated as new soft tissue mimicking materials for ultrasound guided breast biopsy training. A single layer of carnauba wax was added to the lesion surface in order to evaluate its applicability for imaging. In this work we provide measurements of speed of sound sos and acoustic impedance z of some doped non doped rubber based materials dedicated to the development of ultrasound phantoms.

Some common materials used in phantoms for optical imaging e g. These data are expected to be useful for speeding up the preparation of multi organ phantoms which show similar echogenicity to real tissues. From this mixture phantom materials were obtained with speed of sound varying from 1379 3 to 1397 9 m s 1 and an attenuation coefficient having values between 0 29 and 0 94 db cm 1 for a frequency of 1 mhz at 24 c. 1390 to 1500 m s which is still in the range of speed of sound for human tissue.

Silicone may not present satisfying acoustic prop erties for use in ultrasound or photoacoustics culjat et al 2010. Since 1993 polymeric materials have been used widely in. Materials with tailored acoustic properties are of great interest for both the development of tissue mimicking phantoms for ultrasound tests and smart scaffolds for ultrasound mediated tissue engineering and regenerative medicine. Purpose in this work we provide measurements of speed of sound sos and acoustic impedance z of some doped non doped rubber based materials dedicated to the development of ultrasound phantoms.

And dehydration reducing the temporal stability of the phantoms. In this study we assessed the acoustic properties speed of sound acoustic impedance and attenuation. The speed of sound for the phantoms ranged from 1425 4 0 6 to 1480 3 1 7 m s at room temperature. Oil based materials composed of olefin polymers in a mineral oil matrix are another class of tmm.

The ultrasound propagation speed of polymer gels was being characterized. Breast phantoms were produced with a broad range of acoustical properties. Index terms tissue mimicking ultrasound phantom abdominal ultrasound ultrasound propagation speed. These data are expected to be useful for speeding up the preparation of multi organ phantoms which show similar echogenicity to real tissues.
