k-Wave

   Hello,
   I tried using k-wave to simulate a focused ultrasound array with beamforming. However, as the k-wave only support 1D (linear) array, I applied multiple sources. The code works but the problem is the calculation of time delays. Because the standard formula of k-wave is only related to 1D array (y direction) and it information of this direction:

   delay_times_elevation = (transducer.elevation_focus_distance - sqrt( (element_index_elevation*grid_spacing(3)).^2 + transducer.elevation_focus_distance^2 ))./transducer.sound_speed;

   Is there any code for calculating these delays in 2D with the information of both y and z together?

   Thanks

   If you are trying to calculate delays based on geometric steering, it should be trivial to compute based on the Euclidean distance between each element and the focus, along with the sound speed.
