k-Wave

   Hi,

   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.
   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.
   Is there any way to speed up the process if my interest is only the XY plane of z=25mm?

   Thank you in advance,
   Oz

   Unfortunately not - full wave methods like k-Wave have to compute the propagation from the source to that depth. If your medium is homogeneous, you could instead use the Rayleigh integral or another toolbox like focus.
