So all wave effects captured by the wave equation are included, e.g., scattering (reflection / diffraction, etc), refraction, attenuation (wave spreading, absorption), etc.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/what-effect-was-considered-in-simulating-ultrasound-propagation-in-skulltissue#post-8120 Thu, 15 Apr 2021 17:05:30 +0000 tang.shanshan 8120@http://www.k-wave.org/forum/ <p>I am using K wave simulation for ultrasound propagation in a skull-tissue medium. To be specific, my medium is a soft tissue with a layer of skull in it. I am wondering what kind of effects were considered and taken into account into simulation? For instance, propagating speed difference, refraction at the interfaces? I have considered these two effects, but the theoretical RF signal delay profile is still a little bit difference from what I got from K-wave simulation. Is there any other effect, such as mode conversion, was considered in K wave? Thanks!</p> <p>-Shanshan </p>
