I am able to reproduce shear wave displacements profiles similar to the plots in Figures 5 &amp; 6 of [1]. The displacement profiles obtained at different propagation distances (i.e. at different Ny indices) when stresses are given as input to the solver pstdElastic2D() as described in [1] are shown in the figure available at <a href="https://polybox.ethz.ch/index.php/s/ztlYYumUxqQBNgZ" rel="nofollow">https://polybox.ethz.ch/index.php/s/ztlYYumUxqQBNgZ</a>. However, I am curious to know the possible reasons behind obtaining negative displacements in k-Wave as shear wave displacements induced by acoustic radiation force are usually positive similar to the shear wave displacement profiles obtained from FEM simulation and analytical solution as shown in the Figure 3 of [1]. Please feel free to comment your intuitions and suggestions regarding this observation. Thank you. </p> <p>[1] <a href="https://asa.scitation.org/doi/pdf/10.1121/2.0000398?class=pdf" rel="nofollow">https://asa.scitation.org/doi/pdf/10.1121/2.0000398?class=pdf</a> </p> http://www.k-wave.org/forum/topic/how-to-implement-the-arf-induced-shear-wave-propagation#post-7085 Fri, 18 Oct 2019 19:19:57 +0000 Bradley Treeby 7085@http://www.k-wave.org/forum/ <p>Hi bth012,</p> <p>According the article:</p> <p>"to get a volume force as input, we can therefore use an input velocity equal to <code>Fi * dxi / (2 * rho0 * c0)</code>. Finally, this input should be divided by the spatial step dz to ensure proper scaling of the delta function in the z direction."</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/how-to-implement-the-arf-induced-shear-wave-propagation#post-7034 Fri, 06 Sep 2019 19:55:34 +0000 bth012 7034@http://www.k-wave.org/forum/ <p>How to implement the ARF input as a source for the shear wave propagation.<br /> Anybody solving this matter? </p> http://www.k-wave.org/forum/topic/how-to-implement-the-arf-induced-shear-wave-propagation#post-6998 Thu, 15 Aug 2019 22:33:57 +0000 bth012 6998@http://www.k-wave.org/forum/ <p>Hello,</p> <p>I would like to simulate the ARF induced shear wave propagation and compute the displacement. Now I am following some simulation in the article "https://asa.scitation.org/doi/pdf/10.1121/2.0000398"<br /> I have a question. How do I put the ARF data into "pstdElastic2D.m", as an input? This part has not been resolved for a long time.<br /> Could you please give me some comments about that?</p> <p>Thanks, </p>
