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!</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/realistic-tissue-models#post-7879 Mon, 12 Oct 2020 12:00:39 +0000 Anastasiia 7879@http://www.k-wave.org/forum/ <p>Hi Bradley,<br /> 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?<br /> Or would you advise introducing a few larger regions of inhomogeneities rather than pixel-by -pixel?<br /> Thanks a lot!<br /> Kind regards,<br /> Anastasiia. </p>
