In your case, set this to zero for most of the domain, and then set it to your perfusion value wherever the tissue is defined.</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/kwavediffusion-regionally-defining-tissue-perfusion#post-6638 Wed, 07 Nov 2018 01:57:45 +0000 tsimmons 6638@http://www.k-wave.org/forum/ <p>Is there a way to define only a region of tissue perfusion in the kWaveDiffusion class? I'm interested in simulating a region of tissue in the gridspace with a region of non-tissue, so defining perfusion in the entire region doesn't make sense for my application. I can't seem to find anything in the documentation regarding this. If anyone knows if this is possible or has suggestions to implement this, I'd be interested in finding out.</p> <p>Thanks,<br /> Trevor </p>
