If your medium is homogeneous, you could instead use the Rayleigh integral or another toolbox like focus. </p> http://www.k-wave.org/forum/topic/calculating-2d-array-transducer-propagation-in-a-specific-z-depth-only#post-9027 Tue, 30 Jan 2024 16:12:29 +0000 ozshaul 9027@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I'm trying to calculate the propagation from a 2D linear array source to a specific depth. My transducer has a freq. of 3MHz-4MHz and for getting a high enough resolution my grid (spatial and time) has many points. I'm interested only in a specific depth (let's say 25mm) from the transducer plane.<br /> If I use the kspaceFirstOrder3D function (even if I'm using a GPU) it takes a lot of time because it calculates the pressure in every point of the grid.<br /> Is there any way to speed up the process if my interest is only the XY plane of z=25mm? </p> <p>Thank you in advance,<br /> Oz </p>
