Alternatively, you could use the new <a href="http://www.k-wave.org/forum/topic/alpha-version-of-kwavearray-off-grid-sources">kWaveArray class</a>, which allows you to define multiple transducer elements with a finite size.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/how-to-simulate-the-element-width-in-2d-time-reversal-for-a-circular-sensor#post-7970 Wed, 02 Dec 2020 06:13:03 +0000 CY-k 7970@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I am trying to simulate the effect of the element width based on the Example: 2D time reversal for a circular sensor.<br /> I did not change anything in the given example. How can I set the element width instead of using a point detector in thi case?<br /> Thanks!</p> <p>Chen </p>
