As an example, the data from Szabo, T. L. (2004) "Diagnostic ultrasound imaging: inside out" has the following values:</p> <p>sound_speed = 1430;<br /> density = 928;<br /> BonA = 10.3;<br /> alpha_power = 1;<br /> alpha_coeff = 0.6;</p> <p>Using the <code>kWaveTransducer</code> class, it is only possible to have one driving signal. However, you could create your source manually using the time varying source inputs.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/help-regarding-ultrasound-transducer#post-5688 Fri, 23 Sep 2016 10:26:07 +0000 humda 5688@http://www.k-wave.org/forum/ <p>Also I want to use half of transducer elements for one frequency and half of transducer elements for other frequency. Is there any way that i can achieve results by making only one transducer object? </p> http://www.k-wave.org/forum/topic/help-regarding-ultrasound-transducer#post-5687 Fri, 23 Sep 2016 07:17:08 +0000 humda 5687@http://www.k-wave.org/forum/ <p>hello. i wanted to ask if anyone here can tell me whether it is possible to model human body fat in k wave. also what will be the value of medium.alpha_coeff, medium.alpha_power, medium.BonA for fat if we want to design the medium as body fat in ultrasound transducer example in k wave. help needed asap. </p>
