One is using <a href="http://www.k-wave.org/documentation/example_tvsp_equivalent_source_holography.php">holography</a>. Alternatively, if you only have a single point measurement or a line scan, after deconvolving the hydrophone frequency response to get pressure, iteratively update the source amplitude until the measurement and simulation agree. See <a href="http://bug.medphys.ucl.ac.uk/papers/2016-Martin-IEEETUFFC.pdf">here</a> for example.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/matching-simulation-source-strength-with-experiment#post-7253 Wed, 04 Mar 2020 06:39:38 +0000 elliotP 7253@http://www.k-wave.org/forum/ <p>Hi all,</p> <p>How can I convert a hydrophone measurement in the experiment to source strength in a simulation?<br /> For instance, I have an unfocused transducer and I drive with 10 Vpp continuous signal. In the 2D simulation, I put the same transducer geometry for my source and drive with the same time signal. But I am not sure how to determine the source strength. </p> <p>Do you have any idea about this conversion?</p> <p>Best,<br /> Michael </p>
