   In the ultrasound simulation, how to query the value of high frequency ultrasound attenuation constant α0 [dB/(MHz cm)]in different tissues

   You could take a look in the https://itis.swiss/virtual-population/tissue-properties/database/.

   Hi,Brad.
   When I set the frequency to 10MHz and I found that the absorption coefficient of water is 0.25Np/m, now I want to convert it to [dB/(MHz^y cm)].
   alpha_power=1.1,Would be the correct value for medium.alpha_coeff in [dB/(MHz^y cm)] can be obtained with the conversion function : alpha_coeff=0.25*8.686/100/10^1.1 ?

   Kind regards

   Hi LL,

   You can use the function neper2db to check the calculation.
