One of the examples included does exactly this.</p> <p>You can also do this with the regular k-Wave sources by defining <code>source.p</code> as a matrix with the same number of entries as source grid points, it just takes a bit of accounting to make sure the correct source is assigned to the correct physical source.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/multiple-transducer-sources-us-propagation#post-7994 Sun, 10 Jan 2021 01:00:32 +0000 wangk524 7994@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I want to run a simulation for temporal US propagation in a 2D (or 3D) domain, where multiple US point sources act as time varying pressure sources and each of their (distinct) source waveforms are given as a vector (of the same size as kgrid.t_array ---- this can be enforced by padding zeros). </p> <p>From my understanding, the example:<br /> <a href="http://www.k-wave.org/documentation/example_tvsp_transducer_field_patterns.php" rel="nofollow">http://www.k-wave.org/documentation/example_tvsp_transducer_field_patterns.php</a> can simulate the similar problem, but all waveforms in this example have to be the same. I want to simulate the case where each point source produces a different pressure waveform.</p> <p>Yours sincerely<br /> Kevin </p>
