Speed Of Sound In Rubber Based Materials For Ultrasound Phantoms

Up until now no material has been found whose attenuation and speed of sound properties not only mimic those of human soft tissue but are controllable in magnitude.

Speed of sound in rubber based materials for ultrasound phantoms.

Since 1993 polymeric materials have been used widely in. Silicone may not present satisfying acoustic prop erties for use in ultrasound or photoacoustics culjat et al 2010. 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.

These data are expected to be useful for speeding up the preparation of multi organ phantoms which show similar echogenicity to real tissues. 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. 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. Oil based materials composed of olefin polymers in a mineral oil matrix are another class of tmm.

In this study we assessed the acoustic properties speed of sound acoustic impedance and attenuation. And dehydration reducing the temporal stability of the phantoms. Index terms tissue mimicking ultrasound phantom abdominal ultrasound ultrasound propagation speed. 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.

Different silicones ecoflex dragon skin medium and polyurethane. Some common materials used in phantoms for optical imaging e g. 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. 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.

The speed of sound for the phantoms ranged from 1425 4 0 6 to 1480 3 1 7 m s at room temperature. These data are expected to be useful for speeding up the preparation of multi organ phantoms which show similar echogenicity to real tissues. Breast phantoms were produced with a broad range of acoustical properties. A single layer of carnauba wax was added to the lesion surface in order to evaluate its applicability for imaging.
