You can view the sensor mask using <code>plot(mask(1, :), mask(2, :), &#39;x&#39;)</code>. Alternatively, you could convert the Cartesian mask to a binary mask using <code>cart2grid</code> and then plot using <code>imagesc</code>.</p> <p>I hope that answers your question,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/nonuniform-circular-distribution-of-sensors#post-5300 Wed, 04 Nov 2015 16:11:46 +0000 umber 5300@http://www.k-wave.org/forum/ <p>Thank you Brad! Is it possible to add 2 cartesian sensor masks or to use/view them simultaneously? I know this can be done with binary sensor masks. </p> http://www.k-wave.org/forum/topic/nonuniform-circular-distribution-of-sensors#post-5293 Sat, 24 Oct 2015 07:05:18 +0000 Bradley Treeby 5293@http://www.k-wave.org/forum/ <p>Hi umber,</p> <p>You have two options. If you want to use a Cartesian sensor mask, then simply give a list of the (x,y) coordinates of the sensor points. Alternatively, to use a binary sensor mask, then create a binary matrix the same size as the grid, and set value at the grid points corresponding to the desired sensor positions to 1. There is some more information about using Cartesian and binary sensor masks in the k-Wave manual and the examples included in the toolbox.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/nonuniform-circular-distribution-of-sensors#post-5282 Tue, 20 Oct 2015 16:24:54 +0000 umber 5282@http://www.k-wave.org/forum/ <p>Hello! I am new to k wave and need help for the following. I want to place sensors in a non-uniform circular distribution around a pressure source (2D grid). makeCartCircle doesn't allow nonuniform arrangement and makeCircle doesn't give control over the number of sensors and relative positions. How can I implement this? Kindly help. Thanks! </p>
