I will try to do simulation in the way you have written. </p> http://www.k-wave.org/forum/topic/spacing-between-transducer-elements#post-4031 Tue, 29 Oct 2013 17:55:13 +0000 Bradley Treeby 4031@http://www.k-wave.org/forum/ <p>Hi zvalus,</p> <p>The kWaveTransducer class was written to take care of some of the indexing issues that arise when dealing with diagnostic ultrasound transducers in k-Wave. Almost all of its functionality can be replicated by manually defining the source and sensor structures as described in the examples and the k-Wave manual. In your case, I would suggest defining the transducer elements manually rather than using this class. In other words, define a binary source and sensor mask that corresponds to where you want your transducer elements to be located. These are just a list of points in the grid, so can have any geometry or spacing.</p> <p>I hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/spacing-between-transducer-elements#post-4027 Sun, 27 Oct 2013 17:28:20 +0000 zvalus 4027@http://www.k-wave.org/forum/ <p>Hi,<br /> I will try to specify. In this part of program ( example form "Defining An Ultrasound Transducer"):</p> <p>% =========================================================================<br /> % DEFINE THE ULTRASOUND TRANSDUCER<br /> % =========================================================================</p> <p>% physical properties of the transducer<br /> transducer.number_elements = 72; % total number of transducer elements<br /> transducer.element_width = 1; % width of each element [grid points]<br /> transducer.element_length = 12; % length of each element [grid points]<br /> transducer.element_spacing = 0; % spacing (kerf width) between the elements [grid points]<br /> transducer.radius = inf; % radius of curvature of the transducer [m]</p> <p>% =========================================================================</p> <p>The transducer element spacing is fixed (same distance between each element). How this could be changed? </p> http://www.k-wave.org/forum/topic/spacing-between-transducer-elements#post-4026 Sun, 27 Oct 2013 10:06:57 +0000 bencox 4026@http://www.k-wave.org/forum/ <p>Hi zvalus,</p> <p>Do you have a specific k-Wave question? I'm afraid we can't answer everyone's questions on acoustics more generally - much though we'd like to have time to!</p> <p>Ben </p> http://www.k-wave.org/forum/topic/spacing-between-transducer-elements#post-4025 Sat, 26 Oct 2013 12:04:36 +0000 zvalus 4025@http://www.k-wave.org/forum/ <p>Hi,<br /> I tried to simulate an antenna for sonar, however for it optimization different distances between transducers are required. How that could be done? </p>
