Physical parameters of the PA gel phantoms and ex vivo bovine liver and myocardium tissues

Material Density, kg/m3 Sound speed, m/s Volumetric heat capacity, J/C/m3 Non-linearity Attenuation*, Np/cm
PA gel 1044 1544 4460 × 103 3.5   0.01–0.019
Bovine liver 1050 1580 3540 × 103 4.1 0.043–0.097
Bovine heart 1060 1570 3940 × 103 4.1   0.06–0.114

PA = polyacrylamide; HIFU = high-intensity focused ultrasound.

*

Attenuation is given for the frequency range of 1–1.9 MHz (Duck 1990; Khokhlova et al. 2011; Lafon et al. 2005).
