Abstract
A system is provided including an acoustic interface device, configured for coupling to a transducer and to a specimen, the acoustic interface device comprising a material composition having a shear wave attenuation coefficient αS of at least about 5 dB/cm when subjected to an acoustic signal at a frequency between about 200 to 500 kHz. The acoustic interface device may be formed of polytetrafluoroethylene (Teflon®), a perfluoroalkoxy alkane (PFA), polycarbonate (Lexan®), or polyether ether ketone (PEEK). Methods of using the acoustic interface device with a transducer for ultrasonic measurement of a specimen are also disclosed.
