Hi
I'm trying to focus the beam in the elevation direction. But I am not sure it's possible to do it by "elevation_focus_distance". Actually I'm trying to move the focal region in elevation direction in my code. Can i do it in k-wave?
thanks a lot

Hi maryam,
Yes, you can change the elevation focus distance by using the
elevation_focus_distance
input. This allows you to set a single fixed focus distance over the transducer. If you want to use more complicated focusing regimes, you can definesource.u_mask
andsource.ux
(orsource.p_mask
andsource.p
) and define the input signals for each grid point in the source with the appropriate delays.Hope that helps,
Brad.
