You can create it in whatever way is convenient for your application.</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/how-to-use-non-uniform-mediumsound_speed%ef%bc%9f#post-8480 Thu, 17 Mar 2022 15:38:44 +0000 houxc 8480@http://www.k-wave.org/forum/ <p>Hello, I just got in touch with k-Wave package. In the process of simulating photoacoustic signal, I want to take into account the non-uniform characteristics of sound speed, so I want to set different sound speed for different parts (parts are not regular). I read in K-Wave-User that loadImage can be used to load the sound speed of each grid point. But why do I use loadImage to load up some parts and then I use loadImage to load up the speed of sound for each grid point and what does that do? I think the numbers in it are all less than one. Or I misunderstood. </p>
