Note, you will need to multiply by the Gruneisen parameter if you care about absolute values of pressure (e.g., see <a href="https://doi.org/10.1121/1.1920227">here</a>).</p> <p>Brad </p> http://www.k-wave.org/forum/topic/provision-for-acoustic-wave-generation-from-absorption-profile-of-a-3d-tissue#post-6605 Thu, 25 Oct 2018 09:45:09 +0000 prabhakar.amarana 6605@http://www.k-wave.org/forum/ <p>Dear Sir,<br /> I am working on breast cancer detection through simulation of photoacoustic imaging.<br /> Before k-wave simulation, I have done the simulation of light propagation inside the breast tissue model through 3d Monte-Carlo simulation. 3d absorption profile obtained from this simulation was used as a source in the k-wave simulation. Acoustic wave propagation through the medium and its detection using planar array were achieved with k-wave. But I wanted to know whether it is correct to place the absorption profile as a source in the k-wave simulation?<br /> I am also eager to find any mechanism or provision to generate acoustic wave from the absorption profile in the k-wave toolbox so that this generated acoustic wave will become a source in the k-wave simulation. </p>
