Speed of sound in rubber based materials for ultrasound 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. 1390 to 1500 m s which is still in the range of speed of sound for human tissue. Since 1993 polymeric materials have been used widely in.

And dehydration reducing the temporal stability of the phantoms. Some common materials used in phantoms for optical imaging e g. Paraffin gel waxes have been investigated as new soft tissue mimicking materials for ultrasound guided breast biopsy training. Different silicones ecoflex dragon skin medium and polyurethane.

The ultrasound propagation speed of polymer gels was being characterized. In this study we assessed the acoustic properties speed of sound acoustic impedance and attenuation. 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.

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. 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.

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