You could include all the source positions in the source mask, and use a different time-varying source at each source position (ie. including as many time series in <code>source.p</code> as you have source points). In this way you could output zeros on some of the sources. You would have to think a bit about how to construct those time series so they are only non-zero when you want them to be.</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/multiple-source-masks-within-one-simulation#post-8614 Fri, 30 Sep 2022 04:44:24 +0000 johjam 8614@http://www.k-wave.org/forum/ <p>Hi there, </p> <p>Within a single simulation, I would like to:<br /> 1) send ultrasound pulses from sources defined by a unique source mask<br /> 2) wait a few microseconds<br /> 3) send another set of ultrasound pulses defined by a new source mask</p> <p>1) can be done with any of the 3 methods described in the manual.  However, I am requesting advice on how to do 2-3.  I see that I can delay pulses from various grid points from a single source mask, but can I send pulses from a completely different source mask at a different/later time point?</p> <p>A note that some of the grid points in the source mask for the second pulse will overlap with those from the first pulse.</p> <p>It seems that only one source mask can be defined per simulation, is this correct?</p> <p>I suppose the long way to do this is to perform identical experiments with different source masks and time delays, and add them together.</p> <p>Do I have any other options?</p> <p>Cheers,<br /> Jami </p>
