It could be done more precisely I agree!</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/question-about-time-array-creation#post-7104 Fri, 25 Oct 2019 10:41:04 +0000 mkaraoglu 7104@http://www.k-wave.org/forum/ <p>Hi people,</p> <p>I have got a question regarding a *multiplier* that is present to calculate the <code>t_end</code> in the example script: "us_bmode_linear_transducer.m".</p> <p>The part of the script goes as follows:<br /> <pre><code>% create the time array t_end = (Nx * dx) * 2.2 / c0; % [s] kgrid.makeTime(c0, [], t_end);</code></pre> <p>Could I please learn the intuition behind using "2.2" as a multiplier instead of just "2"? My initial assumption was there to be a "2" to make sure we give enough time length for the signal to travel to the end of the computational grid and come back; yet the implementation is done differently. </p>
