   Hi Bradley,
   I would like to model acoustic propagation through a tissue piece. However, I would like it to be more or less realistic. As i understood, even if the tissue piece is more or less homogeneous, it still has scatterers as sources of inhomogeneities. I was wondering, do you think it is a reasonable approach, when modelling a piece of homogeneous tissue to introduce a bit of randomness into the destribution of the speed of sound and density within the slice on a pixel basis? And do think k-wave would have issues with this if every pixel in a slice had somewhat different acoustic parameters?
   Or would you advise introducing a few larger regions of inhomogeneities rather than pixel-by -pixel?
   Thanks a lot!
   Kind regards,
   Anastasiia.

   Hi Anastasiia,

   This is exactly what we do in the B-mode ultrasound imaging examples to give scattering contrast similar to tissue. I think it's a reasonable thing to do. How to set the parameters to exactly match the properties of different tissue types is a more difficult question though!

   Brad.
