Speed Of Sound In Rubber Based Materials For Ultrasound Phantoms

The speed of sound for the phantoms ranged from 1425 4 0 6 to 1480 3 1 7 m s at room temperature.

Speed of sound in rubber based materials for ultrasound phantoms.

A single layer of carnauba wax was added to the lesion surface in order to evaluate its applicability for imaging. 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. Oil based materials composed of olefin polymers in a mineral oil matrix are another class of tmm. 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.

These data are expected to be useful for speeding up the preparation of multi organ phantoms which show similar echogenicity to real tissues. Different silicones ecoflex dragon skin medium and polyurethane. 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. 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.

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. 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. Some common materials used in phantoms for optical imaging e g. Since 1993 polymeric materials have been used widely in.

Index terms tissue mimicking ultrasound phantom abdominal ultrasound ultrasound propagation speed. And dehydration reducing the temporal stability of the 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. 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. Breast phantoms were produced with a broad range of acoustical properties. Silicone may not present satisfying acoustic prop erties for use in ultrasound or photoacoustics culjat et al 2010. In this study we assessed the acoustic properties speed of sound acoustic impedance and attenuation.
