I'm sorry I didn't make it clear.My original intention is to use source.p and source.p_mask ,do you think that can achieve my goal? I have tried it for several months ,but I failed.Can you help me make it happen? It's important to me.Because I'm going to compare my experiments with simulations.By the way, when will the next version come out?<br /> Jack </p> http://www.k-wave.org/forum/topic/using-transducer-class-for-time-reversal#post-7259 Wed, 04 Mar 2020 11:56:46 +0000 Bradley Treeby 7259@http://www.k-wave.org/forum/ <p>Hi Jack,</p> <p>No - the <code>kWaveTransducer</code> class is limited to linear array transducers with rectangular elements aligned with the grid.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/using-transducer-class-for-time-reversal#post-7238 Fri, 21 Feb 2020 11:35:15 +0000 jackYANG 7238@http://www.k-wave.org/forum/ <p>Dear Bradley Treeby<br /> Can you change the kWaveTransducer class to a 64-element or 128-element concave spherical transducer with an opening diameter of 200mm for time reversal,it is best to give the radius of each element, for example, 5mm.This problem has been bothering me for several months, and I really need your help. Any reply will be appreciated. </p> http://www.k-wave.org/forum/topic/using-transducer-class-for-time-reversal#post-4755 Fri, 03 Oct 2014 17:54:28 +0000 Bradley Treeby 4755@http://www.k-wave.org/forum/ <p>Hi k.sous,</p> <p>There is currently no direct way to use an object of the kWaveTransducer class for a time-reversal simulation. However, if you have used a transducer to record the data, you can still do this long hand by creating the appropriate source mask and signal. To illustrate, I've created a simple example based on the <a href="http://www.k-wave.org/documentation/example_us_transducer_as_sensor.php">Using An Ultrasound Transducer As A Sensor Example</a>.</p> <p>You can download the example here: <a href="http://www.k-wave.org/downloads/example_time_reversal_using_transducer.m">example_time_reversal_using_transducer.m</a>. Let me know if you have any questions.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/using-transducer-class-for-time-reversal#post-4750 Tue, 30 Sep 2014 16:15:54 +0000 k.sous 4750@http://www.k-wave.org/forum/ <p>Dear Bradley,<br /> first, I would like to thank you for this useful tool box.<br /> I am currently trying to do time reversal reconstruction using transducer class, but I couldn't find a way to assign the "time_reversal_boundary_data". could you please tell if it is possible to use transducer class for time reversal reconstruction and how.</p> <p>Thank you<br /> Regards </p>
